If I criticize Company A for doing something, and goes around and does the same thing then it'll be very hypocritical of me.
The product-market fit you mentioned doesnt just happen for startup, but for big companies as well. A dollar is a dollar everywhere you go. Just like you found it was OK for your company to sunset a certain product, big companies also decide to do that.
Also, please dont put words into my mouth. I didnt say you dont have a right to say things. You do. But when you do, and please be open to replies.
