Those that complain are 100% in the "don't own FSD" bucket. Prove me wrong. Find me one owner of FSD that is so dis-satisfied that he demanded a refund.
Those who do pay for FSD use terms like "my mind is blown", "it's amazing". They do videos, evangelize the product and wait until midnight on Friday (that's when Tesla releases updates) so that they can test it at 2 am in the morning.
You can make what you will out of this.
To me it shows that product is great already and will be very successful when finished.
The complainers that never used the product are noise.
