You feel very strongly. Fast and centralized platforms were invented enough before binance.
If something happens to binance and their bridge stops working, then you will look at your millions in the blockchain, from which coins cannot be withdrawn.
EOS raised $ 4 billion on ICO, no one needs this platform.
Ethereum and Polkadot make decentralized platforms where you can safely store your funds.
BSC has the exact same security model as ETH
Binance does not have access to your private keys, just as ETH devs don't have access to your private keys. You can self-custody BNB just as you self-custody ETH.
You seem to be thinking about your funds held on Binance exchange, which are not yours, they are Binance's funds.
Sure, Binance can change their protocol whenever they want, but so can ETH (if you haven't noticed, they hardfork about once a month... ex: EIP 1559 is an extremely controversial hardfork which devs are bruteforcing in despite a lot of legitimate pushback)
In BSC, you're trusting Binance devs, in ETH, you're trusting ETH devs.
You don't need a fully decentralized system to host DeFi/NFT projects; you only need enough for them to be open and KYC-less. BSC opted for more centralization with PoS, so they can gain 100x cheaper and faster transactions. A very smart trade.
If regulators ever attempt to control these DeFi projects, projects on ETH are just as vulnerable as BSC (start fining amazon for allowing ETH nodes to be run on aws, and ETH dies; it needs commercial cloud services to run nodes)
And binance-bridge facilitates moving assets from ETH to BSC. If this died, BSC would not die. Also this service does not need to rely on Binance the exchange; it can be done all on-chain
