You can fud as much as you want, but the truth is that:

1-Waves is going to release smart contracts soon, so it's token won't be "stupid"  anymore. Ethereum with PoS when, instead?
2-Having your token issued in a decentralized exchange means that your token can't be shut down by anyone, no aliens, no Putin, no China
3-Having your tokens on a Dex doesn't mean they can't be in a centralized one
