Work in the industry: way too many planners and transit consultants are fixating on too many stops as being a problem, likely since it's the one piece of infrastructure they can control when roads and traffic lights are designed for cars not people.

Depending on the road network and land-uses, removing stops only 200-metres apart to make them 400-metres apart (the industry standard) could decrease access to transit within a 5-minute walk by anywhere from 10-50%+, so it's limited to where you can actually apply it without penalizing (ie. putting them outside of a 7-10-minute walk) so many customers that they look for alternatives.

In Europe stop spacings are much longer even for local routes (over 400-800-metres), but this is because everyone generally lives within walking distance for their errands, so transit is used only for longer, more commute-like trips, where a longer walk for faster travel times makes sense. Accessibility is also less of a priority there so they're less sensitive to requests from seniors and those with disabilities, with many buses not being wheelchair accessible. In US/Canada, a lot of transit riders live over a 20-30-minute (often with hostile walking conditions like crossing highway ramps) walk from the nearest grocery store, school, pharmacy, etc., so they'd oppose adding 2-3-minutes of walking to shorten a 10-minute bus ride.

Moreover, closely spaced stops are really only an issue in older (pre-war) downtowns where frequent stops are the result of decades of requests from residents (especially seniors) and from schools/churches/grocery stores/retirement homes/medical clinics. Out in the suburbs, buses usually bypass most stops, and schedules take that into account. And in places with amazing land-use like Pheonix and Vegas, you have long stretches of nothing so of course there'll be higher average stop spacings.

Lastly, much of the time-savings from express routes (that skip stops) and bus stop consolidation/balancing, is from being more in sync with the lights, which are usually designed for through traffic (ie. a green wave). Transit Signal Priority can help achieve significant savings (over 10-30%+) without removing any stops, though moving stops to after the light makes it more effective (and even that can be politically difficult).
