Are you talking about during FP-? I wasn't on the boards then, so I don't know what was considered evil or not evil.
Personally I do not have a problem with guests utilizing loopholes to maximize their expensive vacations. But during the era of the Great Fastpass+ Debates, there were those who insisted that paper FP- hoarding (using FP- after the return window) was not just evil and sinful and made Walt Disney cry, but also the cause of everything wrong at WDW. The illegal and immoral antics of FP- "Superusers" were blamed for everything: long standby lines, long FP return lines, vacations being ruined, the price of turkey legs, dirty bathrooms, heat rash, making kittens sad, etc.
To back up their claims, there were mathematical studies which supposedly proved that hoarding paper FP- wrecked the standby/Fastpass balance and made everyone wait longer (while at the same time claiming that paper FP- was an unsuccessful underutilized program because it was too complicated and only 10% of park guests were actually using it). The conclusion being that FP+ will end up being far superior, infinitely more fair, standby lines will be shorter, and sunshine and rainbows and unicorns.
The great new FP+ program was going to solve all problems, and once and for all prevent the evil superusers from getting to the park at rope drop and hoarding all the paper FPs. Of course, now we see the truth: instead of running for paper FP at rope drop, now there is a virtual rope drop at midnight 60 days before the park opens to get FP+, and a new wave of exploits. And the same people who vehemently attacked paper FP- hoarders for supposedly "abusing the system" have not much to say when guests exploit the new FP+ loopholes. Most likely because they are using multiple sets of MagicBands themselves.
Like I said, I don't care about guests using loopholes that Disney ignores / encourages / refuses to close. But I find the hypocrisy amusing.
