Minut paid plan?

Hello, is it correct that as of the beginning of June 2021 Minut.com is forcing people to buy a paid plan for using their API’s?

I noticed my Minut devices, 2 in total, no longer were talking properly to Home Assistant and then found out by signing in that they force you to use a paid plan, annual or monthly paid.

To me this is again a company that started with no subscription but now also wants to make more money by forcing you to get a plan. That would be a pity.
I told them already I would like to send them my devices back, now that they are useless to me by not adding them to Home Assistant any longer.
