In that article they provide a list of steps to follow to be safer on Tor. Is that a good list or is there anything else one can do to maintain their privacy?

I switched over to Proton from Gmail about 8-10 months ago and it’s been great so far. Folders and filters have been like what I was used to. The only thing I haven’t played around with much is calendar and invites.

I ended up going for the whole proton bundle since it included the vpn, storage, and custom domains (up to 10 addresses I think)

I used to use the prepaid approach a lot, but recently it seems like some companies are rejecting them. Mainly seeing it happen with subscription based services.
