That's not only DRM, it's the whole subscription model...
... as software that stops to run when the subscription expires.
BTW, Idera/Embacardero, the company actually owner of Delphi/C++ Builder, no longer bumps the installation counters for old versions you actually bought (perpetual licenses), unless you buy one of their very expensive maintenance plans that became compulsory with the recent versions.
So you if re-install on a new computer and you have reached the max installations counter - you may be out of luck (of course, luck could be helped, somehow).
While I understand the need of anti-piracy systems, turning them against paying users in the desperate attempt to get some more money will never end well.
