More like religious prudishness is ruining pretty much everything
Be it christian, islamic, macintologic - it's not a corporate driven problem, it's a problem caused by those with imaginary friends and/or those who worship men in black turtle-necks. If it were a corporate problem, there'd be no corporations producing porn.
It's also a problem of curtailing to a minority, which has been caused by the pendulum swinging too far in the "political correctness" spectrum.
It's also a product of an excessively litigious US society which has thrown away the concept of personal responsibility and replaced it with "foreseeable consequences" which is much more lucrative in a court room.
At the end of the day, I prefer freedom of choice over "freedom from porn", freedom to decide what's appropriate for myself & my family over having to settle for whatever some company selling electronic toys or purveying internet services decides is appropriate for the braying masses.
