The original comment actually criticized Microsoft for a lack of investment to secure their paid and fairly lucrative service that they bought a popular code hosting platform to integrate with.
The opposite we see here: to not criticize them; to blame Microsoft's failure on the critics; and even to discourage any such criticism, are actually more like defending large companies.
It is a lucrative service just because people are lazy and keep buying from Microsoft. Otherwise, they would migrate to better alternatives.
This especially includes governments and other institutional buyers.
