I mean, this is definitely an unpopular opinion. But any post that includes "you guys" or something like it is just rage bait rather than a genuine opinion.
That's just being a jerk with extra steps.
Truth? Any time an opinion comes down to criticising other people as the only support for your opinion, it's a shitty opinion. Why? Because it's flimsy. You made zero effort to back the opinion itself, that instant coffee is "grand". Zero, zilch, nada.
Your only other argument is complication. The "machines and whatnot". Since instant coffee used similar machinery to get into the jar you use to make yours, you might as well say that any coffee you didn't make yourself is better than self brewed. You'd put in about the same amount of "complications" ordering a cup from the closest fast food joint, since you'd have to also drive to a store to buy your instant.
Only if you have your instant delivered to you can you say that you had a less complicated path to a cup of coffee. By that standard, I can tell my kid to make a pot after having ordered everything, and have my fresh coffee be less complicated than your instant, if you made the instant cup yourself.
So, I upvoted your post as being unpopular. But it's low effort, shitposting rage bait, so I shouldn't have.
