On the issue of titles, The Letters Patent were changed for the Cambridge's to allow great grandchildren of the monarch to have titles, rather than wait for Charles to ascend. This is unfair as the same wasn't done for Archie. One might argue that Archie isn't the future son of a sovereign but he's the future grandchild and nephew
The first and most important thing you have to understand about the Royal Family is that it is NOT FAIR. If it were fair, it wouldn’t exist and we would have an Irish style President.
Prince George will become King regardless of whether he wants the job or is suited to it because if he abdicates, why can’t anyone become Head of State?
This is what the Queen has fought to protect for almost 80 years. She has repeatedly shown that she believes this means putting Crown/duty ahead of personal preferences. This is not new.
However, I think the wish to slim down the family is as much to protect individuals as anything else. In recent history, the ‘spare’ children of monarchs have struggled with living a restricted life without purpose and in some cases this has caused actual harm. Even without Epstein, Andrew was obviously targeted by dodgy people who wanted to clean up their reputations. Princess Margaret clearly resented the control exerted by the Queen, but was unable to give up her Royal status.
There really is no reason to have a sprawling Royal Family of cousins trapped by their obligation not to do anything that might harm the family.
All of the people involved in this are normal flawed human beings, but I think the reasons given for not granting more titles are genuine.
However that doesn’t make the institution less toxic.
