@shani Search and maps are indeed their core services. Search, of course, is only half great. The other half they stack the deck with what they want you to see. But those I can at least give a pass on as their core services.

Youtube was acquired (and butchered in many ways by Google, but we're stuck with it because like Walmart there's no room for competition.)

Google Docs? Errr, just no. MS Office, Libre Office, Open Office....those are full featured. Google Docs is a very streamlined product in comparison with reduced features. It's not horrible at what it does, but it's just silly to compare it to a full featured suite. Additionally like with gmail blow...it's watching what you write.

GDrive. It's....remote data storage. There's tons of remote data storage options out there, and there's nothing particularly special about GDrive. IF you want to include it because it's not broken fine, but that's kind of a hard one to get wrong.

Android....Android is not Google. Android is an open source OS. Android has contributions from many companies. Android is part owned by Microsoft (the royalties from Android are what they funneled into XBox to make it look solvent for the past 15 years.) The Google branch of Android that is forced on phones is just Android by contract to get Google's popular digital store and telephony services. After it's loaded to the hilt with their kernel level spyware of course. All of which is absent from stock Android.

Chromium again is not Google. It' is an open source project that features contributions from Google and many other sources. Chrome on the other hand is a security disaster in addition to being a bloated memory hogging mess. If you value security at all (let alone Google's spyware, actual security) you avoid Chrome like the plague.

Gmail is the "best" free mail service because it used market dominance to force out nearly all others. However, you do realize it's scanning your emails and mining everything it can out of them, do you not? It's right in the TOS you agreed to. So yes, they offer you fine email service, in exchange for reading your emails and indexing them to build a total profile on you and everyone you've ever communicated with using everything you and your conversation partners have ever said. Sometimes free is way, way too expensive to be acceptable.

Translate works fine for European languages. It's a joke for Eastern languages. Granted some of that is because by large degree many of those languages just can't be machine translated, they're too contextual, but even Mandarin, which isn't, it misses pretty hard on. Not exactly a niche language.

Chromecast is part of Chromium, not totally a Google product, however they've locked it down behind their logins in any commercial implementation.

Google and Facebook are easily the most sinister companies at least in the Western world, though Amazon is joining them rapidly, and everything they offer is a Faustian bargain like a pedophile with an ice cream truck. It's just a lure to get your consent to do bad things to you. Even knowing all that I still use their product to some measure, because of their scale and scope, it's very difficult not to, but I'm never not aware of precisely what I'm doing, and just how low I'm sinking by doing so.

I don't underestimate the "value" of free products to a public unaware the real currency they're paying. But you're also underestimating the actual cost of these products, despite not paid in reserve currency. Drug dealers also give you some product for "free"....at first.... a great deal, even if it will ruin your life later. Given your locale, the irony shouldn't be lost on you: Imagine an alternate timeline where Goebbels' programs were successful and he lasted into the dawn of the information age (presuming he lived peculiarly long.) What would the organization for digital information and communication he would have built look like? There's more than a fair chance it would look quite a bit like Google and Facebook..... At times I wonder if his programs, weren't actually successful after all.....just moved quietly elsewhere and in the shadows. That kind of control of the public was the heart of what they were after all along, and in the 21'st century the public has voluntarily given it to another group of very similar goals, without the overtly objectionable behavior.
