If what you are looking for is not available, too hard to use, of a bad quality and/or cost too much you will turn to an alternative that is free, fast, easy to use even if is illegal. If you perceive that what are you doing is not actively harming anyone.

It's like if you are running around town looking for a parking spot. You find a place where you could park your car, it's not bothering anyone and doesn't block anyone and anything else it just isn't marked.

If you have a cheap real parking near, you probably wouldn't park in the unmarked spot. But if the first legal alternative is 5 miles away, a private parking charging you 10 bucks every hour, a maximum 5 minutes parking then you probably stop in the unmarked spot.

It's legal ? No. It's actively bothering anyone other than the policeman writing you the ticket if he finds out ? No. You hope that they won't find out, and won't write you a ticket ? of course you do.
