My Sony "smart" TV has updated itself and tried to force me to use a new app
When a device or system is described as "smart", read "spy". See stallman.org/articles/what-mary-had.html.I wouldn't allow anything "smart" in my home, and I urge you to do the same.  As for Netflix, I refuse to let a company know what I watch, or tolerate DRM, or agree to a contract not to give, lend or share copies.  See stallman.org/netflix.html.
