I agree with this, but only for their consumer products. I gave up on the Google Home and went back to Alexa. It was like they just don’t try to use their own products themselves, and once they tick the box of releasing, improvements seem to be nonexistent.
Admittedly, most of my issues were because I have a GSuite account, but when it can’t read my own calendar or set a reminder, you realise they just don’t care. Alexa can read my GSuite calendar just fine.
I always approach Google products with caution.
