According to analysts, Github in 2018 was still losing money when Microsoft acquired them. This is another example of remote work enthusiasts inadvertently undermining their case. If the strategy is "use remote workforce for happier employees and it doesn't matter if you're bleeding money because one of the FAANG companies might swoop in to acquire you" -- you can see why that narrative is not convincing at all to business leaders!
This is the same issue as citing Gitlab's remote work culture while the CEO (Sid Sijbrandij) mentions they're not yet profitable. (https://news.ycombinator.com/item?id=18443014)
Another example is highlighting Elastic's IPO with 700-employee distributed workforce: https://news.ycombinator.com/item?id=18168423
Elastic has also been losing increasing amounts of money for the last 3 years (see their SEC 10-K filings) and has never had a profit since their IPO. They lost $109 million in 2019.
To be fair, it doesn't mean that financial losses should be blamed on remote work -- but you also can't use them as positive case studies either.
tldr: do not cite Gitlab/Github/Elastic as evidence of remote work "being a success" to convince skeptical business managers.
To re-iterate the issue: the Remote Work Movement still needs a slam-dunk-world-beating story of its success. They haven't gotten one yet that convinces skeptical business leaders to fully adopt it.
