ELI5: Why do some products like TV remotes still use infrared while everything else is moving to Bluetooth?

"If it ain't broke, don't fix it". IR remote control is simple, robust, low-tech and extremely widely established. It just works, every manufacturer has experience with it and has the supply chains set up.

You only change it when there is real benefit in doing so. For example, if you need to send more or more complex data than "button has been pushed". One such thing might be a remote that gives haptic or optical feedback, or has a pointer-style functionality on gyroscopic basis. All of that needs more data connectivity than IR can provide, and therefore manufacturers switch to BT.
