That's where you're wrong. FFXIV has not stopped experiencing disconnection issues (I'm on Balmung and I play all the time), I've known many players in GW2 experiencing them, Google.com has gone down quite a few times, Gmail has gone irresponsive quite a bit, I've personally seen GPlus itself bugged out repeatedly over its connections, PSN & XBL I've heard about several times, and I've countless people talking about disconnects elsewhere, but most importantly we're talking about intermittent lost in connectivity (that tends to result in disconnection in older MMOs like FFXI). Skype and Discord have also recently been experiencing such issues as well. In fact, do yourself a favor and look here:

Square Enix is not a customer of the service I'm speaking of any more than you are or anyone else using the internet.
I'm not even going to argue you shouldn't drop your subscription(s), because it is a fact of economics that when you cannot access and play an online game you're subscribed to that it is a waste of money, just like you shouldn't go buy just anything at the store when they've nothing you want or need in the first place. But it's not something you should blame SE for or assume they can do anything about (and I'm saying that as someone that has had more than their fair share of issues with SE).
On that note, they actually did try alleviating the problems with FFXIV on a few fronts. The first time was when they implemented datacentres outside Japan (in their San Francisco building, when 2.0 came out). Players still had issues (EU players most of all), so eventually SE transferred their NA servers to Montreal in Canada (that was however long ago I've forgotten) and EU servers actually to Europe (or did they transfer any to Europe? I'm getting tired, so forgive me).
Yet neither have worked: many EU players will still play on an NA datacentre (for logical reasons like friends, and no one should be blamed for sticking with their friends) and in many cases they're having their connection routed down to places like Silicon Valley (despite the vast inefficiency), then you have many east coast players connecting... where? Yeah, again, through Silicon Valley;
connection between Silicon Valley, California & Montreal, Quebec... see how far and out-of-the-way that is for the mass majority of East Coast & Europe? Yeah, exactly.
That's not true either. Nothing is ever truly free and for technology to advance, it is necessary that people expect better.
