As you painfully shuffle towards your TV in order to increase the volume, you'll mutter to yourself "I've never seen a compelling use of remote control technology."
Once done, you notice it's getting late. Do you continue sitting in the dark or heave yourself up to reach the lightswitch? You smirk. "I'm glad that I'm not dependent on the whims of some corporation."
To be clear, I like technology and automation. I want to automate dangerous tasks and things that cause repetitive stain. Maybe things that need improvement, home air filters for example are changed every 3 months. Is that ideal? Or by measuring the current draw from the blower fan you can see when the filter is getting clogged and change it when needed.
You shouldn't favor your injured limb, but neither should you expose it to unnecessary stress. So if recovery requires parking yourself on the couch, those automations are nice. (Or, alternative, loving friends & family whom you can use to do these things for you :)
And as for the uninjured case: If light switches and TVs are the thing that keeps you from atrophying, you have a problem :)
My last words before I die of frostbite will likely be ‘hey google please please switch the heating back on’, to which the reply will be, for the fifty-eighth time, an apology and an offer to give me web search results on ‘swift the heath in baton’
My Home Assistant instance has only a few devices that are in anyway linked to a third party but even then they have locally accessible API's. Zigbee, Z-Wave, Thread and Matter are all great solutions for this.
Or projects with very difficult build process and no documentation, or unnecessarily complex deployment or too many functional dependencies. Or making the project not very modular, requiring people to deploy a whole VM or container with tenths or hundreds of dependencies bundled in.
The list goes on and on. For example a lot of commercial "open-core" products deploy a lot of tricks to make forks difficult to maintain in the long term.
Many are open source only strictly speaking aka legally, but they discourage REdistribution. Android is an extreme example of this and you can see how HA goes in that direction.
EDIT: There's a company funding HA development and profiting from it using a subscription model...

I will support these allegations of open sourceness as well.
Home Assistant and Matter are a step toward this.
(I still don't like the details, but it's absolutely an improvement.)
