So wait, now we're claiming that anonymous donations to unemployed people working on a gaming podcast that anyone with a brain knows could leave for a job across the country at any moment, and those donations being used to directly improve the podcast for the people left, is "stealing" and "misappropriation"?
Even if Phil and Nick were still there, they could have transformed the podcast into something you hated over time. Or they could have just stopped doing the podcast altogether instead of finding another group of people to do it after they found jobs in other states. Regardless, your donation, your risk.
Instead of letting the donations just sit there unused, they decided to use a small part of them on a gaming PC for someone who couldn't afford one, and who went on to literally talk about PC games he's played on it for hundreds of hours.
You might not like it, but tough shit - it's not "stealing" or "misappropriation" either.
