Good point. But I doubt developers and individuals will be migrating to a centralized chain like TRON. Alternatives like Cardano, EOS, and Tezos are much better options in my own opinion. TRON may go bust, but these smart contract platforms won't. The more ETH 2.0 gets delayed, the better it'll be for the mainstream adoption of alternative smart contract platforms. Even with ETH's current state, there are several "Layer-Two" solutions for scalability. Developers and individuals can simply use these solutions in order to avoid waiting hours for transactions to get confirmed on the Blockchain or paying high fees. It's all a matter of mainstream adoption than anything else. While TRON's technicalities are good, the way it's organized is not. Maybe someone will create "TRON Classic" in the future? With TRON's open source design, anyone can create a better, decentralized version of it.
Nonetheless, the implementation of TRON 4.0 had little to no impact over TRX's price on the market. There doesn't seem to be much difference between this version and the previous version of TRON. The changes are quite minimal if you ask me. It's been nothing but hype in order to pump TRX's price on the market. Luckily, people are starting to notice Justin Sun's schemes which is the reason why prices haven't moved on the market. As the industry becomes mature, there will be a separation between the "good" cryptos and the "bad" ones. And TRX is one of the "bad" ones because it's utterly centralized, defeating the purpose of crypto and Blockchain technology. Just my thoughts
