There is definitely more multi-episode storylines and progression as the show goes on, but the problem remains that most of the time they can’t really keep amazing tech they find, because it would solve too many problems or make things boring.
It does occasionally happen though. Over the seasons they do accrue an impressive collection of tech which does carry over and is used in episodes going forward.
While I don’t know how it elsewhere, I used to work at one of the big corpos.
Among many other interest groups like a book club or vegan club, there was an internal interest group for LGBT employees. It’s them who had to self-organise and push for the rainbow company logo and the like against pushback from leadership.
So while ultimately the decision to allow it probably was just a marketing calculation, it was actual LGBT employees making it happen, who had to work hard to get the company to recognize them, and definitely not the company pretending to care. The company didn’t care, and LGBT employees have to fight that to make these things happen.
