And, while these can be legitimate concerns, there are millions of websites out there. Millions.
And people get scared when they hear about a few dozen websites being shut down or domain names being seized. That's something like a fraction of a fraction of a percent. You are probably more likely to be struck by lightning than to have your website shut down. Even more so if you're not doing anything illegal or questionable on your website.
That's not to minimize concerns but to put things into perspective.
The greater risk to your website(s) is not "Big Brother" watching your website, but rather you not watching your website.
Think about it... How many people have no idea how much they are spending each month on their sites? How much they are making each month on their sites? What their gross is? What their net profits are?
People worry about the government tracking PayPal payments so they can collect tax on income, but how many of those people keep good track of incoming and outgoing PayPal payments so they actually know where they stand financially?
How many set aside money, if need be, to pay taxes at the end of the year?
What about links? Do all your website links go somewhere? Do you have broken links to pages, graphics or external websites?
Do you have unused images and pages cluttering your website's server?
Do you have half-finished pages on your site? Pages you meant to come back to later but forgot about?
Are there pages with no meta tags? No incoming links from your navigation bar or other pages on your site? Pages with no titles? No descriptions?
Do you have a robots.txt file?
Are all of your buy buttons working?
The way things are right now, you're more likely to lose your website due to your own negligence than you are by having some government agency take it away. Granted, there are legitimate concerns about government meddling online, but many people would probably do well to worry less about "Big Brother" watching their websites and worry more about keeping an eye on their own sites themselves to make sure everything is working right.
After all, if dozens of people couldn't buy your product because your buy button wasn't working, how much would that cost you?
