It's up to you, if you don't care about privacy issues then you can count on it. I trust and invest in ethereum for the profit it brings, so I won't see anything wrong with ethereum. The move to ethereum's POS is a must because there is no way to solve its problems like gas fees and scalability if it doesn't move to POS and can't reduce gas fees, I think people will also leave it soon and choose other blockchains. So it doesn't matter whether it becomes more centralized or not.
Honestly, people investing in cryptocurrencies today are more concerned with profits than privacy. If you want anonymity we have bitcoin, even if eth is decentralized it cant compete with bitcoin.
Most people view Ethereum as an investment tool (not a currency). They wouldn't care if it becomes heavily centralized as long as their pockets are filled with money. Only a very small minority actually care about decentralization, as they're true believers of the technology underpinning ETH. As long as money talks, don't expect things to get better anytime soon.
At least, Vitalik proposed a roadmap to help tackle the issues of centralization surrounding the Blockchain. I'm hopeful ETH will become more decentralized with subsequent network upgrades. Despite becoming less-decentralized with PoS, it's still a far better option than heavily centralized coins such as XRP, BNB, or Solana. I don't think ETH's position on the market will change just because it lost some decentralization after the upgrade. Who knows if it lives alongside BTC for generations? Just my opinion
