I'm sitting here wondering if it's possible to replace the software on smart TVs with something other than what came prepackaged. Something open source, something we can control properly.

I mean, I doubt that any software will just plug and play even if you can somehow get the TV to load it.... and I'm sure with enough time and reverse engineering you could cobble it together, but, I mean, something for everyone that you can just flash onto the TV and be rid of the garbage software that came with it.
