Even YC isn't clean in this regard. They funded a startup called InstallMonetizer that promulgated the drive-by installer problem: https://news.ycombinator.com/item?id=5092711 . There's a great quote from that post:
> You can make a lot of money doing all kinds of popular things -- pimping women, selling drugs, selling 'likes' on facebook, selling botnets that create fake clicks on advertisers, ponzi schemes, etc. Some are illegal, some are just barely legal, but they are all damaging to someone. This line of business is known as 'scummy' and InstallMonetizer is plain 'scummy'.
Yes we have to blame those who perpetrate the behavior, but we also have to blame ourselves for not being more aggressive in sounding the alarm. For many influential people who could have put a stop to this, the Upton Sinclair quote applies:
> It is difficult to get a man to understand something, when his salary depends on his not understanding it.
Governments are partly to blame here, for not addressing platform economies. But some are working on it [1].

For services, there is more scope to prevent misuse, but it's a never-ending battle.
We now have to live with a bunch mostly sensible though occasionally over-sensitive rules to make sure we don't try to trick and cheat our non-tech brethren.
We of course still have plenty of other super-techy places we can play—: Linux, Raspberry Pies, Embedded Devices, the whole of server-side internet.
Yet we still moan because someone has walled a bit of it off to protect ordinary people from charlatans.
Boo-hoo.
