One of the most intense rivalries in tech right now is Facebook versus Snapchat.

The two companies are in the midst of heated battle for social network supremacy that's caused Facebook to attempt multiple clones of Snapchat's core features, most notably with Instagram Stories.

Employees from Snap have remained mostly quietly about Facebook's aggressive behavior in recent months. But Snap's vice president of product, Tom Conrad, broke that silence on Thursday with a snarky tweet to Instagram product chief Kevin Weil.

The tweet from Conrad, which he quickly deleted, was in response to a picture Weil posted of his (very cute!) kids Thursday morning that also asked for a caption contest.

Conrad, who follows Weil on Twitter, decided to make the obvious joke that Instagram's Stories feature looks almost identical to Snapchat Stories:

While it's hard to argue that the caption doesn't fit the photo, it did stir up reactions from other people in the tech community who saw Conrad's tweet before it was deleted, like VC investors Chris Sacca and Josh Elman:

Conrad's feelings about Facebook's copying efforts are also evidenced by the tweets he's liked on Twitter, including this recent one about the Snapchat clone that recently debuted in the Messenger app:

Snap CEO Evan Spiegel has yet to publicly speak on Facebook's copying of his app, but his celebrity fiancée Miranda Kerr recently said she was "appalled" by Facebook's actions and asked, "How do they sleep at night?"
