I see a few people who don't want to switch due to the hassle it would take with changing email addresses, presumably because they use one of the @proton.me email domains. Get your own email domain! It's super cheap (if you choose one of the new TLDs, it can be as low as few dollars a year), the setup isn't really hard - you just change a few DNS values, and that's basically it - you can use whatever email you want that ends with your domain. It might take a while to slowly replace all your @proton.me emails with your domain one, but if you're not in a hurry and change any old mail you see during your day-to-day activities, you'll eventually be done with it, and you can set up mail forwarding to your domain for mail that arrives to your old @proton.me address.
And if you ever need to move to a different provider, you just change the DNS records again to a new provider, and your email will start coming to the new one immediately.
Mind sharing how you do it? I'd love to do this in regards to US politics, and especially AI, since most of the AI post frustrate me with how much bullshit it is.
