The founder of blockchain.com recently bragged about how their users made up 22% of transactions for bitcoin in the last 24h: https://twitter.com/OneMorePeter/status/1128392025466974210?s=20
Their service is deliberately choosing to make transactions larger then they have to by not using segwit. When they dont use segwit the transactions take up more space, which in turn requires you to pay more in fees and everyone else has to pay more because less transactions fit on the chain.

Blockstreem green Samurai wallet BRD wallet (make sure to activate segwit in settings) Electrum BTC.com And many more
You know you are using segwit if your btc adress starts with a "3" or "bc1"
