Why famous internet companies of the world avoid porn content and sexual content?

Why famous internet companies of the world avoid porn content and sexual content?
Whether there are legal restrictions or is there another reason?
for example in Instagram,picasso,flickr or in social pages like facebook and google plus.

I recently read a news that says "Google images search service" wants to limit sexual content in its results.

Porn industry is a money-making industry. Why do they ignore it? Do they realy adhere to ethics?
It is a taboo? Or an illegal act? Or an unusual act?

Google has had their 'safe-search' for a long time.

instagram, picasso, flickr, facebook and google plus all have underage users.

It's not a matter of 'ignoring it' or not recognizing that the porn industry exists, it's that you are asking them to break the law.

The internet companies can get shut down by providing porn, and they would rather stay in business.

If you want all-porn, all the time, there are plenty of sites you can visit on the internet and can drown yourself in it, print out pictures and stories and bathe yourself in, and even make clothing out of the images if you want. Nowadays you can even print out edible 3D images to feed yourself with it. Just because there's a money-making industry behind nearly everything or everything, this doesn't mean that these commercial markets and products are appropriate for all ages and all peoples across the world at all times to see them.

You must be young, not a parent or take the amoral approach to parenting. Regardless of how "normal" pornography is, it's not something that belongs in places that are easily-accessible to children where they can stumble upon it accidentally. Or even adults who don't care to see it, for that matter. Even if these sites are purposely making pornography more difficult to find on their services, it's not eliminating sexual content in any capacity.

Laws vary depending on where you live, but I suspect in most places it's not legal to show pornographic images to children. By sites allowing such situations to take place, they're not only opening themselves up to problems with the law (decency / obscenity laws, for instance), but lawsuits by disgruntled users.

In regards to Google, their change was to make users looking for sexual content be more specific about what they're looking for. They haven't hidden anything or removed anything more than normal, rather if you want porn on Google images, you need to spell out what you want in more detail, rather than using generic terms to find sexualized content.

Because there are alot of prudish people out there who would refuse to use sites that have porn on them. So yeah, it's a taboo, basically.

But it's also worth noting that not all big forbid sexual content. Twitter allows porn. Amazon and Netlfix both sell/rent adult-only (NC-17) movies. Google does allow adult content on some of its services, so does Yahoo. Even eBay allows adult only items, albeit with major restrictions.
