Well one reasoned objection
...is that the 'Unlimited' ISPs were also selling bandwidth that they couldn't provide. If someone sells me unlimited bandwidth at 1Mb/sec or whatever; I expect to be able to draw on that 24/7...that is what I've been sold and that is what I expect to be able to redeem.
Say I go into a pub and order a pint. The landlord brings me back a half and says "sorry mate, those pissheads in the corner are really slurping it up tonight"...and then charges me for a pint anyway...same thing.
I work on the internet and am a heavy user. On my own, I can do in 2-5Gb/day without going near anything that could be described as "mickeytaking freetardery". Linux users can do in a few Gb just staying current. Heavy use != freetardery...there are many perfectly kosher reasons that people use a lot of intertubes.
ISPs in the early days were very much 'boom and bust'...you announced the service and obtained infrastructure that could support a certain number of users. In the early days, your service was popular because your infrastructure was undersubscribed. Gradually you packed more and more users onto that infrastructure. Along the way you noted that your infrastructure could support *more* than the rated number of users as not everybody was ramming the pipes all the time. So you crammed more and more users onto it. Eventually the service slowed down and became more unreliable. So then you upgrade your infrastructure to cope with more users and start the cycle again. If at upgrade time you had 1) Spent the cash or 2) Left it too long in the 'unreliable' state so that your reputation was trashed; you went bust. That's putting it simplistically and there are loads of other reasons ISPs went bust...there are always casualties in early adoption.
Blaming the heavy users is only ever an excuse. If you resell what you don't have, you are going to run into problems. And implying that all heavy use is down to freetardery with no exceptions is untrue.
You're just swallowing and regurgitating the ISPs' PR; and that's where your downvotes come from.
