You are right, if one reads it very charitably but in my experience "a lot of people like X because they hate Y" is very often used as a writing device to make a point and denigrate X. In this case, no, it doesn't say that all people who work from home hate their jobs but it says that the probably of people working from home hating their jobs is higher without proof to further their argument. I've seen a lot of that on both sides of the fence in the WFH.

So, when Wework's CEO says that people who work from home are the least engaged, when I read in this thread that people who don't want to work from home must not like their family (paraphrasing), I take it to mean for what it is, an insult in order to push one's favoured view and I dislike this.
