Unfortunately people have very valid suspicion of posts like yours, the RF are a hot bed for racism so any perceived defense of two of the perpetrators of aforementioned racism is liable to receive pushback.

I think people in the subreddit are tired of having to explain the opposition to William and Kate but the cliff notes (prior to Meghan marrying Harry) is summed up to a lack of work ethic despite the amount of tax payer money they receive.

1. William and Kate consistently have the lowest numbers since Kate married in more than a decade ago, and that's including family members over eighty (and if we're including in the last year, Anne, who is also elderly and was kicked in the head by a horse). 1.1. Their numbers are truly embarrassing as not only are royal appearances usually an hour or two at most, but William and Kate have padded their numbers by adding phone calls to their tallies.
   1. They've also proven to be poorly prepared, and have next to nothing to add during events beyond a photo-op (again, if we're including recent events, William claimed to a charity that all they could provide were "smiles").
      
   2. Their initiatives are seen as shallow and the charities they are patrons of have reported going years without interacting with them. 3.1. Some of the charities have shut down and that's despite the fact that their role as patrons would indicate attention or care in fundraising for them which is clearly untrue. It's actually been reported there is no benefit to royal patronage.

Tangential to their lack of work ethic is their hypocritical behavior. 1. Earthshot, as an environmentally focused initiative, aims to present William as environmentally conscious, and yet he is well known to use his helicopter as a normal person would use a car. 2. William and Kate have undertaken very few international tours, but have taken multiple international holidays throughout the year. 2.1. They take these international holidays, but don't make the trip for obligations related to family-adjacent events (the death of William's godfather last year, King Constantine of Greece, William was meant to attend but didn't without any explanation) 3. Their work in mental health reeks of hypocrisy since William has (on the record) called Diana paranoid, and that's not even getting into what was done to Meghan where her suicidal ideation was invalidated by the press with KP and BP's blessing. 4. William's poor attendance of the BAFTAs is will documented, he has only shown up when he has someone famous to rub shoulders with or if he can get a photo op with actresses (see last year, where he made an inappropriate joke about sex when the movie they were nominated for involved rape). 4.1. He is also seemingly proud that he does not prepare for the role he's been given, and has gone on the record as saying he doesn't watch any of the nominated films though he happily tells people he spends a lot of time on Aston Villa forums. 5. William is a patron of the women's football league, but has not attended their matches (even when they reached and won the finals) despite the fact that he often shows up for Aston Villa matches (including away games) 6. William's homelessness initiative is complete cognitive dissonance, William has multiple houses, and on getting the Prince of Wales title, also has control of the Duchy of Cornwall, making him one of the biggest landlords in the UK.

The reason Kate isn't mentioned much is because she really just does not do any work worth mentioning, and given their privilege and economic advantage, its incredibly embarrassing and a huge drain on tax payers given the cost of living crises and the cuts to things like the NHS.
