By "still are like that" you mean hold a grudge against Microsoft? Seeing as this story takes place in the 90's, I think it makes sense that a child programming nerd would be pissed at Microsoft.
Remember that antitrust actions came to head when Microsoft was
sued by the federal government, 20 states, and the District of Columbia in 1998. After the trial, Bill Gates was widely revealed as being a snobbish shady bully, not the benevolent coding genius he portrayed himself as. It also came to light that he had been seeking affairs with female employees. It hurt his public persona so badly that he resigned his position as CEO in 2000, and started to focus on Gates Foundation activities. He needed to reform his image so he could pretend to be a "good rich guy." Bill remained director of the board until 2020.
By that timeline, it matches what you said about things becoming more open by the late 90's/early 2000's. Microsoft was ordered to cease its predatory monopolizing under threat of being split up.
