Probably just confirmation bias given the fact that a) you mostly read articles/blogs targeted at SWE professionals, and b) software engineers are far more likely to blog about their career experience than any other profession.
I'm sure if you read some trade magazines targeted at lawyers, etc you'd find similar sentiments.
Another, slightly more cynical interpretation is that software engineers are "special snowflakes" who are much more likely than legal/financial/medical professionals to complain about long hours and/or burnout. Interestingly those three professions all have gruelingly long hours and require you to "pay your dues" early in you career. Yet those professionals seem to complain far less, perhaps because the long hours are an expected part of their culture. After all, in finance people typically brag about how long they stayed at the office. So there is clearly some difference in work culture between the professions.
I somewhat agree with your cynical interpretation, but I might tweak it a little bit to be more forgiving: It's a matter of expectations. SWE work, for the most part over the last 20-30 years, (until very recently, at least to my eyes) has been perceived as "creative", almost "artistic" work, whereas the day to day is much much more in line with some weird combination of banking (often high stress, shifting goals, high impact of externalities, one small cog in a giant machine) and blue collar production work. This not even counting the drastic shifts I've seen in the last 5-10 years to commoditize SWE work. (not a value judgement, just an observation)
Most of my friends and family who went into finance did so knowing what they were getting into, some even _wanting_ that. It definitely cultivates a different culture and set of expectations. (There are definitely some CSers I knew who love the grind, but I don't think I'm making a stretch to assert they were the minority, and often were within a specific slice of CS that requires that more similar culture)
