I have a 7 series TV and it came with some arguably bloatware apps but I could remove them (from the menu, not uninstall them, which leaves me with not even a few mb to install Spotify). The one thing I can't get rid of is a stupid program guide I have to go over when going from sources to settings. That's it so far. I'm in Europe and disagreed with any data collection they asked about. Does it now even still do the ACR? Are they going to retroactively install me ads? Are there specific domain names one should block? Alternative firmwares?
