I mean, that's the web summed up in a single sentence. What started as a way to view text and pictures online is now more complicated than many operating systems. You cram all that stuff into a single binary, give lackluster and ever changing controls to manage all that and call it the future. Never attempt to break down the functionality across several dedicated clients that do only one thing and do it well, that's for losers.
But I somehow disagree with your statement in that it seems to imply that the people designing that garbage are naive or don't really think about the consequences of what they're doing. That might have been true in the early days of the web when nobody knew exactly what it was going to be but it's clearly not the case now.
The folks at Google know exactly what they are doing, making browsers more complicated and easier to interconnect with smartphone is win/win for them. It makes it harder to make a competing browser (anybody attempting to make a new browser these days basically has to fork Chrome or Firefox, and generally they go with the former), you need huge developer resources to maintain and optimize it (look at how hard Firefox is struggling to keep up despite the large number of people working full time on it) and while the big G doesn't control Windows, Mac or Linux they do control Chrome and Android so they have a huge incentive to push everything possible away from desktop OSs and into Chrome. They want Chrome to be the OS.
Google is 90's Microsoft with better PR. Well actually it's worse than that because MS didn't usually have access to my private data while google knows almost everything about their users if they have an Android phone and use gmail.
