"The precedent upholding this bs is you can sell services/goods with licenses, then have another company buy you, keep all the profits from that and not honor the contracts. One can do this perpetually and grift customers and completely undermine all contracts."
Someting like this has happened in the U.S. with unscrupulous solar panel + loan companies. You sign a contract to get the company to install solar panels on your house, and you pay for it with a lien. Usually the company has to maintain the installation. But there have been cases where the original company goes bankrupt, and another company buys all of the loans. The new company demands the client to continue to pay them monthly, but refuses to maintain the system any more, claiming they bought the loans, not the service agreements.
Did not (and won't) happen to me, but it's been in the news in the U.S.
