Without all you have mentioned, just by looking at the market, you'll realize that defi has lost its purpose and now dying. We have so many copycat in the market that It will be hard to differentiate the real from the fake. All the Defi been launched are all about quick money and not wanting to contribute to the development of the industry which is while hackers are finding it very easy to hack the platform as same tricks can be used for all the platforms out there.

Defi were supposed to be decentralized meaning no centralized features yet we hear stories of funds getting locked when hacks occurs to prevent to hacking from moving the money. While that is a good thing, it goes against all the features of decentralization which means the Defi are not decentralized but centralized equaling a fail technology.
