ProtonMail Compares Apple to Mafia, Says App Was Forced Into In-App Purchases in 2018
Apple apparently told ProtonMail "out of the blue" that it was required to add an in-app purchase option to stay in the ‌App Store‌. Similar to the situations with HEY and Wordpress earlier this year, ProtonMail had a mention of paid plans in the app, which prompted Apple to ask for the same subscription options to be offered via in-app purchase.

  • Email username
    You might want to consider getting a domain name of your own and then get email hosting which will allow you to set up your email in the way you want. If you don't want to have to manage and pay for domain name and email hosting, you may try premium email services like Space Email, Proton Mail etc. With then you'll definitely be able to get a username/email address of your choice.

  • us What's a good (under $500, preferably lower than $200 though) android for geeks?
    Ironically, Pixels are the best for de-Googling. GrapheneOS requires a Pixel, as does CalyxOS for the most part. If you don't want your money going to Google, a used/refurb Pixel gets around that in my opinion. Source: 12 months ago
