It’s not just old Huslters. If eBay were not allowed to prevent explicit pornography from being sold on its website, it would have a much less valuable business, and fewer people would get value from it. Just as an example, it would end up being blocked by “family friendly” web filters that are popular with businesses, schools, and families.
Unless you think that businesses, schools, and families should also be prohibited from blocking pornography, or should otherwise be forced to facilitate access to eBay, your suggestion is untenable from a business perspective.
eBay is undoubtedly blocked by numerous work filters because it is not really relevant for doing most jobs. They manage just fine.
Besides this is a ridiculous strawman. "If you allow people to sell Dr. Suess books, you must therefore also plaster the front page in explicit pornography." Obviously not.
The Internet is increasingly winner-take-all and is controlled by fewer and fewer larger and larger companies. Allowing a handful of corporations unrestricted reign to dictate what we are allowed to say to each other is antithetical to a free society. Reductio ad absurdum arguments are not going to help you when cabal of corporate censors with no accountability decide to eject you from society for daring to question the intellectual fashion of the moment.
I have not made a straw-man argument. Laws must be written precisely, and it’s entirely appropriate to test proposed changes to law by applying them to specific cases of fact.
You may have identified a real problem in society, but you have not proposed a viable solution.
Unless you think that businesses, schools, and families should also be prohibited from blocking pornography, or should otherwise be forced to facilitate access to eBay, your suggestion is untenable from a business perspective.
