I am privacy conscious so I would like to use my proton.me account, but I wanted some advice. Should I use my gmail account for career related purposes or should a proton.me address be fine?
How is choosing MS not making a conscious decision about privacy? Companies choose MS specifically because it has very strong controls to protect information. Same with workspaces to a lesser degree.
That's the baseline, how all US-based services leak data, but obviously, how much data they leak, depends on how much data is stored unencrypted on their servers. And that's where GMail is significantly worse than most services.
