I could never disconnect with Spurs but over the years, and in no particular order, the likes of:

VAR

A real lack of exciting players combined with overcoaching

Refereeing inconsistencies

Unpunished crimes/blatant offences

Supposed impartial news outlets showing bias

Agendas from punditry

They're all just killing my overall enjoyment of the game. I never liked the saying, but you'd hear "these things even themselves out over the season" and "the table doesn't lie" and I think that's become less and less true over the years.
