Imagine being so dumb as to think your data is safe with Google...

They don't give a shit about their user's "data security". They sell their user's data to the highest bidder. Google's just trying to use that as a pretext to edge out their competitors because they're taking away ad revenue from users who would otherwise have to use the Gmail web UI.

I began plans to ditch Gmail after all the internal leaks post 2020 election showing they were going to start censoring and meddling in their users political lives, and then I finally ditched Gmail last year for Protonmail, which has pretty good feature parity and was able to import all my Google data. They do have a small monthly subscription fee, but I'm willing to pay that if it means they won't sell my data and will Google some competition.
