There are people reading this forum who earn mid 6-figure incomes in Silicon Valley. There are others that are first-year students at, say, Nigerian universities (median income $ 800). $ 150 can mean an hour of work or 1 1/2 months.
And the people who need to not eat for two months to pay for this software can do anything this software does with free software. You can image diff with Gimp, you can track versions through LibreOffice, you can three or four way merge using Meld or any other tool.
This is a shiny tool for developers from rich countries, not a necessity to develop code. I think your argument is valid for things like the price of an Apple dev account ($99 per year if you want to publish an app and no option for out-of-store distribution) but this is nothing more than a shiny UI that will save your minutes per day.
Not meaning to be rude, but how is this relevant? Should no one ever buy or discuss anything that someone else, somewhere else couldn't afford? That is just not realistic and I think you are ascribing a fragility to that student that is condescending. That student knows how the world works, including all of its distribution of wealth issues. Give them some credit, they can take care of themselves. As for the software, there are lots of free alternatives.
Sure. And the correct way to deal with that is to recognize that everybody is speaking from their own perspective, relative to their own circumstances and income, not to demand that every person's posts contain an encyclopaedic rundown of every possible perspective every other person on the planet may have on a price.
Because to expect the latter is both ridiculous and impossible.
