altcoins has long become VC playground literally most of projects nowadays exist because VC funding otherwise the founder won't even bother creating projects, it's always money that they're after, this is why sometime people consider altcoin to be just VC coin and I think it's no different with this acquisition if it's really to be happening in the future.
that's why the true investment for crypto will always be bitcoin, even institutional investors know this and always put big chunk of money to bitcoin instead of diversifying to altcoins, they won't be buying things from altcoin because they know it's just VC's scheme.
And that's why 99% of altcoins are centralized. They're funded by VCs driven by their own interests. Do you think they'll support truly-decentralized projects with anonymous developers/founders? Of course not! It's why Bitcoin is so different from alts. The community has been maintaining it after Satoshi left the project. All without funding from the aforementioned entities (as far as I'm aware).
Polygon is no different from Ethereum and the others. It will put VCs' own interests above all else. This means sacrificing decentralization in favor of convenience (scalability). Despite the transition to POL, market prices have barely moved. All eyes are on BTC to reach a new ATH. Once it does, alts like POL and the likes will go to the moon. So there's that. With so many L2 projects built on ETH these days, I wonder if Polygon will have a future?

The migration seem to be just the change in name. I don't find any difference prior to being MATIC or now POL. They do provide some technical jargon but the real experience is not much different. The fees are are similar or more than other L2s and there's not much new things happening on the network. It's also a matter of hype but also of the technology involved that increases the speed and decreases the price. The hype war is being led by TON while technologically newer L2 like zksync, manta, Injective EVM seem to impress me.
