Big issue I have with Technic of late is the demise of Power Functions. The cost inflation associated with Control+ is a whole legitimate topic of its own. But my main complaint is that my kid and her friends are much better off with old Power Functions style controllers. Driving with a phone app is a really deficient experience compared to a classic RC-styled controller. We have some Buwizz control bricks and in that case alternate apps exist such that you can use gamepads, but I don't know if Control+ apps support that. In any case, young kids' hands can barely hold those, plus I'm not excited about them jumping around attached to my phone as they drive. The apps are not nearly as good a solution for kid play as the Power Functions controllers, across the board---cost, durability, accessibility, screen time, versatility, etc..
I would also really love a generic pneumatics set, not one buried in an expensive adult-oriented model.
