Good morning.

(Here’s the sign-up, if you don’t already get California Today by email.)

As consumers, workers and communities push back against the seemingly boundless power and wealth of big tech companies, they’re starting to find it may be harder than it sounds to quit corporations that provide now-crucial services.

My colleague Kate Conger, who covers privacy, policy and labor for The Times’s Tech team, wrote about a Berkeley City Council proposal to boycott Amazon:

Under state law, no city in California is allowed to share data with Immigration and Customs Enforcement. But city officials have been left to determine how they’ll comply with the law — and many cities are now scrutinizing the behavior of the tech companies they rely on for city services.

Richmond approved an ordinance in June that will end its contract with Vigilant Solutions, a data analytics company that does business with ICE. Other Bay Area cities, including Oakland, Berkeley and Alameda are weighing similar proposals that, if enacted, could lead the cities to sever ties with tech giants like Amazon and Microsoft.

Berkeley’s City Council is currently weighing a proposal to boycott Amazon in protest against the tech giant’s contracts with ICE and Customs and Border Protection. Given Amazon’s business relationships with these agencies, Berkeley should “commit to finding ethical alternatives,” two City Council members, Kriss Worthington and Cheryl Davila, wrote in a memo. The City Council is also scrutinizing its business with Microsoft and Thompson Reuters over the companies’ ICE contracts.
