I really hope this will not be the case.

It's a real shit show for a small business to correctly setup their MDM and account sync. One of the hardest parts is getting those shitty devices into the Apple registry, i.e. connecting the device with a Business (Account).

I wonder why they're doing it – it's just bull crap to close any account having more than one game purchased.

Do you experience problems with Element (the Client) or with Matrix? And what types of problems do you encounter?

I don't understand whether you want another platform or another client to use Matrix – from my perspective, it would be the best to report those problems.
