ye your pearls before swine, lest they trample them
under their feet, and turn again and rend you."
King James Bible
seems like a Chinese company has learnt that lesson the hard way?

"I really wanted to believe that Mancunians could be trusted with nice things. Just over a fortnight ago, a Chinese company called Mobike brought 1,000 shiny new silver and orange bikes to my city. Unlockable with a smartphone and available to rent for just 50p for half an hour, they could be ridden wherever you liked within Manchester and Salford and, crucially, could be left anywhere public once you were done....
Two weeks on and I fear that a dream is all it was. There are Mobikes in the canal, Mobikes in bins and I am fed up with following the app to a residential street where there is clearly a Mobike stashed in someone’s garden. ...
On Thursday, none of the eight bikes showing on the app as being near my house were actually there. I was so incensed when I reached the location of the ninth and could see it locked away in a backyard that I lost control of my senses and knocked on the door. A young man opened it and I asked nicely if I could rent the bike. He looked surprised and said, no, it was his, and anyway, he needed it later. I explained that was not how the system worked, that the bikes were public, and that if everyone was as selfish as him the whole thing would collapse. He rolled his eyes and told me I would be trespassing if I dared try to fetch it."
