Does anybody here use Mycroft voice assistant? How does it compare to Amazon Alexa and Google Assistant?

I spent a year of my life writing an extension to it that allowed you to control various streaming services and Kodi with it. When I released it, a bunch of guys in their developer community bitched me out at length because I licenced it under the AGPL and they wanted MIT.
It pretty much killed any interest I had in the product.

It was ok but their timely demise and gosh of custom hardware seemed to prematurely end the project
- Did they go completely out of business? I was an early kickstart backer and was a bit pissed they took new orders after years of delays then filled those and very few of the kickstart backers.
  It is/was a great idea and project but their unethical business practices (IMO) make me want to avoid the project.
  
  From memory, they got sued for patent infringement from a patent troll, and had to end the project(at least as far as the hardware goes). No idea how much or if any of it is true. The project is still available as open source. Runs reasonably well on a raspberry pi. Setup can be a little finicky for the microphone.

It's pretty good and you can create custom commands relatively easy. I wanted to use it for my smart plugs, which works by linking it to Openhab, but some hardware is not supported so I don't actively use it. It only sucks that it loses its connection often so you have to log in to the website and link it again.

- Although the name sounds like it, “Mycroft” isn’t something developed by Microsoft Just a heads up if I interpreted your comment correctly
  
  Oh... I misread the question. Thanks for the heads-up!
