Surely there are some benefits with ease of use, and for sure there is going to be ongoing interest (whether from the merchant or customer) regarding whether there are ways to reduce fees.. and I would imagine that anything going through Apple pay is going to have some kind of fee.. and maybe Apple will be inspired to lower their fees in the event that there is meaningful/significant competition... ..., an advantage of the device maker, and for sure Apple can be a bit stingy when allowing third parties to use features built into their device.. and whether third parties need to request permission might inspire the use of other devices (taking away some of the incentive of having to carry several devices rather than just one)...

Q:
How it’s possible they were so stupid to keep their private key on plain text on a cloud service?
A:

They were no less stupid than the average cryptocurrency investor who keeps his coins on CEX, online wallet, or cloud/email. A fool who has an empty wallet and a fool who has 100 000 BTC in a crypto wallet are still fools who face the same fate. They could have lived like kings all their lives and stayed under the radar, but it still required intelligence they obviously did not have.
The more that we find out, the more implausible the whole story seems -... yet we do know that some dumb peeps do exist in this world, but somehow they might end up coming across fortunes of BTC or some other cryptos. Something is missing in this story in terms of transferring online and into one wallet rather than maybe having some coins spread in various other places..
