FOSS and privacy are 2 completely different things. If Gmail software was FOSS his points would still be relevant. Try to dislike people for the right reasons at least.

Hey, makes no difference to me. There are a lot of reasons to protect yourself and your privacy online. Ads is one. Government snooping is another. Hackers stealing your data is another. Rogue employees snooping on your data is another (countless stories of Facebook employees reading their exes private messages, I’m sure it’s happened at Google too). Being logged into Gmail makes it possible to track you on nearly any website you visit since Google trackers can phone home with your unique identifiers is another!

Good UX is a piss-poor reason to not care for your digital privacy, not just because it’s less important than the nuts and bolts, but because there are providers that offer encryption with good UX. Skiff is on par with Gmail. Proton isn’t far off. They both offer free tiers. Skiff almost offers the same amount of free storage as Gmail. The only difference is you don’t have that gross feeling like someone could stalk you on every website you visit, or read your messages.

Just advising you to use protection, for your benefit. But go ahead, bang the hooker without a condom. It doesn’t impact me in the slightest whether you heed this advice. I say this as someone who was one of the earliest adopters of Gmail. I had a Gmail account before they were publicly available. I don’t use that shit anymore.
