From my perspective the best part of all of this is that Bitcoin is still alive and is getting more publicity than any amount of money could have bought it! That being said I believe that all of this noise will get people to understand what Bitcoin is, why it's important, and eventually will understand that the only way to get it to succeed and create a more just and equitable world for all will be to hold Bitcoin in self custody. IMO they will realize that to do this in the most effective way that they will need to minimize their spheres of trust and will learn about how to create their own entropy with simple analog methods offline (such as flipping coins 256 times) and creating their own BIP 39 seeds. They'll also learn how to run their own nodes for verification and to transmit and receive their own bitcoin transactions. These actions will allow for the dollar price of Bitcoin to break free from their manipulation efforts and will eventually get us to a better bitcoin centric world that will break the monopoly of value creation and distribution from centralized control.
I will have to disagree that the promotion of Bitcoin by these institutional investors will make people understand decentralization. The truth is that they are promoting centralization because they are mainly focused on profit maximization. You might be surprised that very soon people will assume that the only means of investment in Bitcoin is through third parties. They will only become aware of self-custody if any of these major ETF companies for bankrupt or make them lose their funds. These investors might have some influence over the market but the decentralized nature of the Bitcoin space will still make it very difficult to be manipulated.
