They balance that out with the non warranty support and bad press if it goes south.
Well sure. Apple partnering with Google to make sure that Airdrop to Android works properly would likely increase the instances of support calls that Apple might have to field in relation to Airdrop. And yes indeed, if it fails to work properly, ("goes south") then Apple would face some bad press.
Here's the thing, though. Both of those things are also likely to happen if Apple breaks Google's implementation of Airdrop on Android. Now as far as "non-warranty support" goes, Apple could just wave off a caller with "that's not supported functionality", which is probably something they already are well-trained to do. But there really is no way to avoid the bad press because "things went south", especially when those things go south because you intentionally made them go south.
Well they hacked apples devices and Apple is well within their source to change things up. And it’s perfectly valid for Apple to protect its stuff.
Sure. Apple has many rights - they have a right to change their source, they have a right to break Airdrop, and they even have a right to just completely drop Airdrop or any other functionality from future phones if they so wish to do so. Nobody is debating on what Apple has a "right" to do.
It is, however, also perfectly valid for consumers, reporters, YouTube commentators, and MacRumors forum commenters to point out when Apple (or anyone else for that matter) exercise such rights in a way that only benefits themselves and is otherwise detrimental to their customers.
Google would appear as the bad “guy” here hacking apples protocols.
I wouldn't be so sure about that. As it stands right now, Google has provided additional functionality to both Apple and Pixel users without any apparent downside to either Apple users or Pixel users. If Apple were to intentionally break this functionality, they'd be hurting their own customers without providing really any benefit in return.
Now, usually when Apple does something like this, they use "security" as the justification. And, of course, there is definitely a large subset of Apple users who will just blindly accept such a justification. To those users, yes, absolutely, Google are probably going to be seen as the bad guy. Google doesn't really care about those users, though, because Apple has a lock on them. The vast majority of those users will never even consider anything other than an iPhone.
The
other 50-ish percent of iOS users who use Apple phones for no other reason than "it is what I prefer", the ones Google is actively trying to court over to Android - who those users perceive as being the "bad guy" is much less certain.
Apple is scrappy is what I will say.
They aren't the only ones who are.
