GPLv2 was clearly intended to let you change the software on your devices. In some countries, GPLv2 already prohibits tivoization.

However, big tech found an exploit: In some countries, GPLv2 allows tivoization. This was not intended by the authors of the GPLv2. There was another exploit involving patent licenses, and a reverse exploit about license termination that allowed some developers to extort some users. They fixed these and made it the GPLv3. It's a bugfix release, not anything new. You only don't like it if you relied on the bugs.

Well, that's not really mutually exclusive with what I said. Those who called it GPLv3 consider it's a bugfix, those who decided to stay on GPLv2 consider it's a new licence.
