Evangelists and comfort code
Good luck mining that data without bias.
A special type of Internet troll is the technology evangelist. They boast how perfect it is, compare simplified examples of their tech to real-world samples of other tech, and tell everyone they're doing it wrong. This pollutes and derails normal online discussions. The worst part is that limited examples never demonstrate anything, whether for or against, so the whole argument is pointless.
Then there's comfort code - the software that everyone knows and uses even if it's awful and the users are awful. Contractors love Java + Spring + Hibernate and everything they touch must use it. Nevermind that their code skills are awful and Spring started showing its age years ago. There are whole communities around using that tech stack. Whatever you want to do can be found online and nobody questions a tech stack that has limitless copy & paste solutions.
