I did not saw anyone criticizing MSTR besides those who think they are doing wrong to use their profits as leverage to take loans and then investing that loan back into BTC. I think you raise this issue in a topic and I came to know about it from your topic as well. And there are thos who criticize him for donating to devs to create more centralized products as in some videos shared by some OGz here, says, Micheal Saylor don't like decentralization don't know the reality.

But don't know the truth too so, I don't criticize him because his buying played an important role in pumping the price and he is holding onto a massive profit that he can book anytime and dump the market but he is using that profit to buy more even. That's a positive thing too but don't know why people really criticize him. Maybe just a sentiment that big brother in the house getting all the pie hehe.
