The hardware bought by a company can't be bought and used by the competitor.

I own the InkPad Color 2. It runs on an, I guess, embedded Linux not Android. So no Android apps.
You can upload your e-books through USB or download them e.g. through the PockeBook-Shop or the installed webbrowser.
In my opinion you can't meet everyones needs. The moment a desired person chooses a different romantic partner, you've got grounds to start wars.
If I had a dedicated NAS and a server for the services, I would choose the consistent path and keep it separated. So I would run nextcloud and jellyfin on the server and let them access storage on the NAS.
It depends on where you live. In Germany they can use whatever they find in a raid against you. So you could get additional charges.
PocketBook also has nice readers and as far as I know they run an embedded Linux as OS.
Basically, yes, they couldn't use them. The old 2FA had a really weird implementation...
Back then I was deciding between Posteo and mailbox.
I choose mailbox because, at least at the time, they had unlimited calendars and Posteo only offered 3 free ones.
Also the website of mailbox seemed more respectable / unspectacular / boring than Posteo. Posteos website got me some typical start-up vibes, means hoping for fast growth and quick exit. But there I guess I was wrong.
mailbox.org has a web app, so no need for a client app.
And Posteo also supports POP3, IMAP and SMTP, so you can use every mail client with support for it.
