This, 100%. I think Protonmail gives people a false sense of security. I want to protect myself from companies that collect my data to profile me and sell that profile to people with money who want to manipulate me (aka advertisers). All of the parties I communicate with via email use more insecure providers, so even if Protonmail was perfectly secure, my emails are vulnerable anyway. I think it's important to keep in mind that the providers you're sending email to also have the ability to scan those emails and profile you based on them. As an additional layer of protection from this profiling, it's helpful to use a wildcard alias both when sending and recieving mail to make it harder (but not impossible) for third parties to build a single profile of you.
Personally, I've switched from Protonmail to Fastmail. Yes, Fastmail is in Australia which has draconian state surviellance laws and will comply with state requests for your data and share it with other countries. But you can't assume that any other email provider won't, as evidenced by what Protonmail just did. And Fastmail has better features for protecting you from being profiled, such as unlimited wildcard aliases, and the ability to create filters and deactivate aliases directly from incoming messages, in addition to a far better overall email experience.
Well, it only gives a false sense of security to people who are not paying attention. It literally says that it will give information to governments with a valid search warrant. They never have hidden that, ever. While, yes, it is true that if you send an email to a gmail, yahoo mail, hotmail, etc, those companies don't have access to all of your emails. That's the best one can hope for. They can't read my payments to the company that I lease my office from, my payments to my VOIP provider, etc. I agree with using multiple emails - I must have 8 or 10 of them. And not for nothing. One I use for only personal friends and acquaintance, so I don't get junk emails, one for only personal business accounts, one for my business accounts, some for general information, one I use as junk email when I have to fill in an email and don't know if I want to use that service, etc. And most of them are email names like YRV782SQLN483@hotmail.com.
You are right about Protonmail and Fastmail giving up info to legit governmental agency subpoenas. It's just obvious. Any company will do this, no matter what.
I chose tutanota after an extensive search, because I don't want aliases, I want completely separate email accounts, because if you have aliases, they all still come to the same exact account and I would still have to wade through all the emails. The filters really don't do it for me personally.
And tutanota was the least expensive option that I found. Emails are only $1 per month - $12 per year, while Protonmail is $5 per month after the first email address, at least that is what I remembered at the time. So that is 500% more in cost. So if I have Protonmail, it would cost me $240 per year (if paid annually, otherwise more if paid monthly) for 5 extra email accounts, while tutanota is $60 per year.
