We have never been "owners." having licensed to use something does not mean having the property, so much so that autodesk already for a few years no longer activates pre-2010 licenses. then users with autocad lt 2010 and prec. if they have to reinstall the product after formatting or on new pcs, they use it to the maximum for 30 days and then they attack (I know something because I have a pissed customer who in its time bought 10 and now has remained with a fist of flies)
I'm not experienced, but I can say that once you bought autocad and that copy was yours forever, you owned the license. Even today if you have an old license, type autocad 2000 can be activated by local legally. Then obviously you have to have a pc compatible with an antique software, but autodesk can't help us.
then about 10/15 years ago, the software houses changed the terms and indicated that they granted the right to use revoked at their discretion. to activate the license you had to connect the software to the manufacturer's website that checked the validity and activated it. in the substance did not change much that.
the fact that today, autocad 2010 is no longer activable leaves me shocked. It seems to me that the license was permanent. I can be wrong, but I don't remember that limitations were indicated. as well as today if you buy officie (not 365) is a license permamente, usable toricamente even in 50 years.
after other autodesk time introduced the concept according to which, they offer software substantially to rent. you pay a monthly or annual tot and they allow the use of a software always updated. I think other software houses have aligned themselves with this system today.

via the online license verification system today you can buy a time (month or year) of use of autocad. but then what remains to the customer? He doesn't have the perpetual license. He sells the remaining time of use. But what is forbidden by the eula except for some cases and however behind payment.
In this way the software houses found the method to avoid remaining on the licensing market a few years ago, preventing the application of the right to resale.
making a comparison with cars, it is like saying: cars from now on are granted only leasing. the car that cost 20'000 euros, now costs 5'000 euros per year, and every 5 years you change your car with a new one. in this way all the used will disappear and if you want a car people who first spent 20'000 euros every 10 years, now in the same time will have to spend 50'000 if you can't use the bike.
Is there any mistake as written? I could remember badly and I'm not up to date so I hope I got some crab.
