Yep, this is correct. Not to mention the maintenance cost of .NET Framework going up every year because the library ecosystem moves onwards, eventually, from legacy behaviors. And also, bumping the .NET version from 8 to 9 or 9 to 10 is typically a very small effort for most. I think what the OP is describing is working for a software cost center where they don't value the software system itself.
