That being said - if I were to make a guess, I would speculate that this came down to equity thinking.
For example, in my workplace we host a public service that is targeted to low income people, because others are expected to pay for the service.
But because of the "equity lens" they also offer it to certain named groups of people - immigrants, the black community, seniors, LGBTQ+, - because those groups are known to have more low income people (or some portion of the group, in the case of LBGTQ+).
Frankly, it's stupid, there are plenty of individuals from the "marginalized" groups who are very well off - there are extremely wealthy seniors, gay men are actually more likely to be rich - but they have access to the service.
In this case, I wonder if some idiot said, oh, gay men are marginalized, and more likely to get HPV cancers, so we need to allow them this service at any age, even though it is a waste of money.
Because all that is important is to be seen to be applying the equity lens.
But, as I said, that's a guess.
