I think another reason is that the BTC community (not just on this forum alone) has promoted Ledger (and Trezor too) for a very long time as recommended hardware wallets, i am talking of before the community knew they were lying about wallets secrets never leaving the secure element and a lot of other lies and security flaws from Ledger.

So it is kind of difficult to convince people now that Ledger isn't recommended, especially people who don't know what they are doing and can't do their own research. I've had to answer a couple of questions from newbies who query why Ledger is 'no longer' recommended and i am sure it won't be the last time.
