There was poor governance and management that debilitated their ability to function during the 3 year bear market. And they got their act together. In the mean time, more product market fit was made apparent and upgrades to the instruction set for arbitrary execution was done to the network and continues to this day.
The Ethereum network consists of many-to-many relationships for approval transactions for ERC20 tokens to interact with other smart contracts. This wasn't even foreseeable 18 months ago, and 18 months before that the ERC20 protocol wasn't even ratified.
Really? If that energy consumption problem wasn't there, what advantages does Ethereum have over Bitcoin? Would it even exist, since it offers many of the same features?
That's why the past few years have seen a rise in fungible and non-fungible tokens (average merit of those aside for the sake of argument, since this is just answering the question "it offers many of the same features"), pretty much all of which are hosted on Ethereum or Ethereum code forks like Binance Smart Chain.
I think there's a decent chance they may eventually pivot a bit and rebrand Polkadot or Substrate as an Ethereum layer 2 platform. They already seem to be leaning in that direction a bit.
No shit, if you take away the defining feature of something, you will be left with very of value indeed.

There are a lot of people with perverse biases. Many of the comments enthusiastically defending Bitcoin are people who are sitting on BTC and have watched it get pummelled due to its ludicrous enormous-energy-for-something-that-does-nothing-for-humanity reality (seriously -- if I see one more chart comparing the entirety of the financial industry with Bitcoin. The former powers the entire world. The latter powers some speculators, criminals, and a minuscule number of legitimate transactions).
