All iOS issues with Google software, I suspect, have more to do with Apple being dicks to Google than with Google fucking up. Remember, Apple is really trying hard to rid iOS of all Google programs. Remember Apple Maps?
I don't think it's just Apple's fault. Every time I try to use the Youtube app on my iPhone, I can never find the things I'm looking for, because they seem to ignore all of Apple's interaction guidelines and implement the Android UI instead.
The other day I was trying to send a link to a friend: instead of clicking the standard share icon, you have to click the arrow (that looks like an email forward?), which pops up a non-standard share UI instead of the standard sheet. Never mind the fact that to dismiss a video you have to first swipe it down (minimizing it into some bizarre picture-in-picture frame), then slide it off from there, instead of using a "Back" button/gesture like every other app in iOS.
Got any actual evidence for this? Yes, I remember Apple Maps; I worked on the team. Apple Maps was the result of Apple being smart and not wanting to be beholden to Google Maps forever; eventually you have to roll your own.
And yet, here we are five years later, and Google Maps is still on the iPhone, shows no evidence of leaving, and Google's iOS apps are ALL still present and better than ever, and Google is still the default search bar in Safari. Meanwhile, Apple Maps is a great product too and has been worked on and polished for several years. "Remember Apple Maps" betrays a mindset where you read one article a few hours after it was released, half a decade ago, and you have no updated impression of the product at all. Apple Maps is, in fact, rock-solid for me right now. It is, in fact, now superior to Google Maps for transit directions, and in some other ways.
So really, I'm not sure what you are talking about, at all.
I wouldn't be so sure. I run Google apps on Android, and although I'm not sure the situation has gotten worse, it definitely hasn't gotten better. I can concur that navigation will crash without warning mid-route, maps will suddenly decide I'm somewhere very, very far away (and change the results list to "match"), and so on. It's not unusable by any means, but it could stand improvement.
Back when iOS 6 was released with Apple Maps and no YouTube, Google could be forgiven for problems with their replacement apps, as Apple had somewhat surprised them with the timing of the removals. That was three years ago, though. In the present tense, it's hard to imagine what you mean; it's not like iOS has some library to inject crashes into Google apps, or Apple is preventing updates to those apps from being published on the store (as ruled out by the frequency of updates).
There's the fact that iOS currently doesn't allow replacing the system hooks for Maps and Safari with Google Maps and Chrome (or any other store apps), but that's not the type of problem the parent was complaining about.
If you look at YouTube on android, I see evidence that they are f'ing up there in how advertisements are presented.
Put yourself on 144p quality. Watch a few videos till you get to an ad. It seems like they disregard your preference and pump up to 4k for your ad, which sucks when it takes 2 minutes to download a 30 second advertisement.
The crash issues I had with google map was on Android. I check the reviews on Google Play Store, it is not just me or my Android devices, almost everyone had that crash issues at that time.
I can't figure out how Google can release any software like that.
