In most EU countries when you want to take out a loan, the bank takes a look at your current status ( employment, expenses, family, etc.) and debt history stored by the central bank ( which is basically you had a loan of 10k for 5 years, don't own anything anymore) and judge based on that if you're credit worthy or not.
Let's look at it from a different perspective. If a coworker and I build a service in my garage from the ground up where I let users pay $100/mo month-to-month, $75/mo for a six month agreement, or $50/mo for a twelve month agreement, you're saying it's fine to agree to the twelve month term, get the 50% discount for a few months, and then cancel your card even though the only reason I offered such a steep discount in the first place is because you promised you'd pay me for twelve months?
I do not owe them the money yet they sold the debt. Nobody cares ... I now have a default on my credit reference.
The whole industry is crooked
You can make up any persona on the account and they wont know who to pursue.
The account name and address can really be anything... and this is also true for the CC on file.
But we are talking about really deceptive sales practices by Adobe. Fighting fire with fire in this instance seems particularly reasonable.
That aside, engaging this tactic on transactions with merchants with reasonable cancellation terms would be borderline fraud. If you use the services and they satisfied your needs, you really should be paying for them.
