I'm not cheering for the layoffs, of course, nor am I necessarily in favour of monopolies and the consolidation of the gaming industry (although, in this instance, I think it's probably a positive thing for fans of Blizzard IPs). But layoffs during this kind of merger/buyout are expected. Microsoft has its own legal departments, payroll departments, marketing departments, etc, and while they might need expanding slightly as the company grows/absorbs new companies, they don't need an entire second company's worth of those departments.
These layoffs were about cutting redundancy rather than just chasing short-term profits. It sucks for the people who were laid off either way, but I think it's good to be realistic about why they happened.
And also just websites compressing images without the user getting any input. A meme that goes from Facebook to Twitter to Reddit to Twitter to Tumblr to Reddit to here will likely be compressed every time it gets reuploaded. Most social media sites use some form of image compression.
And it obviously doesn't help that artefacts from compression are multiplicative.
