Based from his response here, I think he is just a troll.
As a customer, I feel entitled to take advantage of everything I can. I don't understand the negativity around it. Us consumers have a salary each month, and we are supposed to get everything we can out of it. It's that simple.
For example, I run Spotify with an ad blocker, so I don't have to pay for it. And years ago, when they limited the amount of minutes of music you could listen to every month, I made tons of accounts to bypass that limitation. Why? Because, in the unlikely case they go out of business, by then some other service would've appeared, run by someone who thinks he won't commit the same mistakes the owners of the previous service made.
Common sense says my system of abandoning/taking services is not sustainable in the long term, but by now it hasn't failed me. And I'm also sure a sizable percent of people do the same I do. Am I a troll just because I'm open about it?
Let's set aside any moral/ethical implications of ab/using free services for a moment.
The problem for you as a customer is that once the service closes it might take some time to find a new service.
Second, your time is valuable too. Making multiple free accounts to save $10 a month is an activity which might make perfect sense for a poor college student but would draw comparisons with Mr. Burns if you are a middle-aged high wage earner.

As defined: a person who habitually relies on or exploits others and gives nothing in return.
It's ok to use free services, to abuse them, especially if you are not capable of paying. It's understandable. A lot of people do that. But to be honest in saying that you don't really care about the company failing or if they go bankrupt for whatever reason even if you are an avid user because a new service will pop up that is free. Seems to be morally wrong.
Your reasoning also shows that you don't have your own company or you're not a developer creating or selling softwares. Because if you are, you would be afraid of people like you who will abuse your company the way you are abusing it now. This is just an assumption. I might be wrong.
