Two block explorers shut down due to lack of funding. Only possible on Algorand.

Check all.info is the current block explorer on algorand 
Alternative https://explorer.perawallet.app

Algorand still has 2+ explorers

Slightly typo there the explorer is allo.info

Also Algorand Foundation tried for months to acquire algoscan but the team weren't cooperating

I think you can get the same analytics in allo.info , algoexplorer was also built by the myAlgo team 

Finally Vitalik was also sim swapped earlier this year , not trying to defend Staci but sim swaps happens all the time

Both AlgoScan & AlgoExplorer were useful for tracing the MyAlgo hack due to lack of analytics tools in the Algorand ecosystem. 

The Algorand foundation is just laughable altogether (with recent CEO SIM swap & Oct 2022 unreported hack)
