I had to lookup the backstory. I obviously cannot know all of the context, but... honest question: why would people make fun of a comic about such deeply personal tragedy? To me it seems tone-deaf to say the least.
Plenty of people make fun of webcomics that developed a serious plot and actual characterization over time (MegaTokyo and Questionable Content both come to mind). This one went from 0-100 in one strip.
It seemed to a lot of people that Tim Buckley realized "oh hey I don't want to have a baby in the strip" and decided to get a cheap emotional punchline while he was writing himself out of that self-inflicted hole.
But when your comic has less depth than your average Garfield comic, it doesn't work out so great.
It was a disaster. He insulted his stairs. He had load-bearing drywall. None of the windows matched, making a big ugly box even uglier. The foundation settled and the addition separated from the original house. He fucked up the plumbing real bad and swamped his yard multiple times. He tried to get certified as an inspector because no professional inspectors would touch his work.
It quickly became a legend, and is fondly remembered even today as one of the good old stories of the internet.
Sometimes someone with poor talents and awe-inspiring arrogance does something so monumentally stupid, tasteless, and just plain bad, that it gains a life of its own. Sometimes that's bad siding, sometimes that's bad comics.

From the article:
> The last strip to mention Lilah’s pregnancy prior to “Loss” had been published 10 installments and nearly a month prior, and readers found the sudden attempt at gravity hilarious. So they did what the internet does: turned “Loss” — again, a comic strip about miscarriage — into a running joke
