Wrong, Robert. Having been experienced with this in the past, here's what happens:

The provider in question installs/enables Remote Desktop Services (formerly known as Terminal Services, so you need to update yourself on the new name) which effectively removes the connection limit. This is the case with Windows 2008 and I can confirm that there is no 'patching' involved at this point. The Remote Desktop Services is activated on a trial license that lasts for 90 days.

Once these 90 days run out, there's 3 options:
- Patch said server to evade the need for installing the license
- Buy a license
- Reinstall your OS all over again to get another 90 day trial

That's where you're correct - most patch it. Some do an OS reinstall. Purchasing the license itself is not worth it for any provider because their services run on a margin so low it would run into a loss if they went legal with this licensing.
