I'm not sure what point you're trying to make. A 20-30% jump in a grocery bill is unprecedented in my life time. I'm skeptical it's even that low for most. Pre-pandemic, I was buying eggs for 1.39, they're 2.49 now. Jarred spaghetti sauce used to be 1.99, it's 3.49 now if I catch a sale. I used to be able to regularly buy chicken breast for like 1.49-1.99, now if it's less than 3 I buy as much as I can afford and freeze it. This time of year in my area, corn would usually be on sale 4/$1. The cheapest it's gotten is $0.79.
Just repeat ad nauseam for everything. The other day I was in the store thinking to myself, "I'm not sure I can afford convenience foods like canned beans." Canned. Fucking. Beans. The luxury.
They seem to want to be obstinate, so while I don't agree, I'll take a stab at answering the question:
The link they posted has this bit right at the top:
The fundamental belief seems to be that however you obtained the software, paid or not, you should be free to do literally whatever you want with it.
Where I really disagree is that proprietary software (like half of the answers in this fucking thread lol) are fundamentally not scams. A "scam" implies something that one party, the patsy, is not aware of.
