Has anyone used Proton Business Suite rather than Google's for a startup?

I'm considering doing so. It's much better priced, I would like to keep adwords separate as all the horror stories I've seen posted here, and the end-to-end encrypted communications could be valuable to my startup. Has anyone used Proton's business suite in a startup environment?

may i ask whats the horror with adwords?

email wise whats cumbersome with proton is it tries to upsell me again and again with its add-ons.

on google workspace i can say the best advantage is how almost 90% other sites out there supports signing in with google. and it's also cheap at $6 per head, and it doesnt harass you with upsells unlike proton.

I am bootstraping, and have used proton for years as my only email, but have my own email now, and am slowly backing out of proton. The horrible way that they extort by limiting and degrading a service is only part of the problem.They degraded email replies at one point, to a tiny "page" with less than one full line of text. There is more, but proton is not worth the effort to remember and detail all of it.

I will use google or any other service for building up an advertising presence. And keep the proton, until everything is moved. And then again, pragmatism might decide in favor of useing the proton service, but only as the core of my business is seperate,and will spread my add bucks around, so I feel safe. Currently have NO guggle anything, because of past denial of service, and will only use them for the advertising side as well.

In my opinion, E2EE comes with too many compromises to be worth it for most people and/or companies. Proton wasn't evolving quickly enough, so I switched to Fastmail.

Email aside, no CardDav/CalDav is a dealbreaker for me.

Proton suffers from the Lavabit problem but worse, it pretends to offer security and freedom when it does neither and acts as a tool of foreign governments to abuse individuals. Use your own GPG keys and better clients, preferably with self-hosting in Iceland or Sweden.
