I don't think anyone thinks this is a "trick", at least not from what have read here anyway.
No, but I would be mad if I had to buy GM tires, GM oil, and GM wiper blades to make my car even start in the morning. "Sorry Fred, you use a (gasp) Fram oil filter, so we can't allow you to drive on public streets"
Totally agree.
I think that what many of us are thinking, and we have seen multiple times in the past, is that you buy this premium device, and then the company decides to change direction (Hive is a recent example) or the company goes bankrupt (TONS of examples here). Once either of these happen, these expensive devices are totally worthless. They become e-waste which is a growing problem.
I don't wish for your company to have any issues, however abandonment of a product for whatever reason has been a very common and troubling pattern over the years. Many of us were burned by this, (sometimes multiple times and with some very high dollar losses) and why we insist on local control. That is the main attraction to Hubitat and other systems like Home Assistant that do not rely on the cloud.
Additionally, there is sometimes lag when using cloud services that isn't present when communication happens locally. There are many who don't have reliable internet, have metered internet, or live off-grid. The internet can go down, there can be DDOS attacks on someone's server, and other issues that could prevent things from working properly.
It doesn't have to be specifically Telnet, but that is a great example of how things should work.
