This might be a silly question, but in what ways did it get worse? Is it the size of the keyboard changing, the predictions not being as good anymore or something else?
With my knowledge of tech companies, I’m not exactly surprised, but I’m not an iPhone user and struggling to understand how a keyboard of all things could get worse.

I agree with this. I think the most important thing is not necessarily the original company releasing their proprietary code (although that would be nice), but it being easy (and legal!) for hackers to reverse engineer and/or build on top of the platform.
The irony is that, since most such products will have some GPL’d code in there somewhere, most products already basically have such a requirement, thanks to the section requiring complete corresponding source including installation instructions. Hopefully, the Vizio case will establish the precedent that users, as well as copyright holders, can take action against such companies.
