First of all, it's not obvious to most lay people. Second, I wouldn't have a problem if that was the reason stuff stopped working, but if Smart TV makers / sellers explicitly advertise certain apps, those apps damn well better have a decent life. I bought mine and days later my favorite Roku app (Spotify) decided to shut down that app for something like a year. Nothing to do with hardware advancements, they just made an intentional decision to de-prioritize a device I had already been sold and it didn't keep up.
