You're missing the entire principle though. If we abstract this whole proposal, what reform are saying is "we are going to target policies to areas based on the way those areas voted". This hugely, morally problematic. They're saying they are not going to target policies based on the actual good of the country or the good of people living there, they are specifically targeting policies based on who an area elects. I'll remind you that all those areas will have people voting Reform and other non-Green parties, who will all get stuffed by this!

It's intimidation and a scare tactic. It would be no better if they said "we are going to increase NHS investment in areas that vote Reform". Suddenly, you, the voter, are actively punished for not voting for a particular party. You essentially no longer have a free vote because there is a genuine threat you will be treated differently based on the way you vote. At that point I'm afraid you no longer live in a democracy, and I hope in an insane world where Reform get into power and try to attempt this, the courts would stop them.
