Sort of.
As a supporter, the PL and FA Cup wins stand as amazing accomplishments, and no-one can take them away from us. They're not tainted.
But those moments could have meant that we were on our way to establishing ourselves as a bigger presence in UK football. There was an opportunity to grow the fanbase, improve the stadium, work with bigger and better commercial partners, etc. None of these were guaranteed and in some ways they might be considered distractions, but they matter commercially, they matter for the city, they matter for the future of the club. Frankly, they matter for the pride of the fanbase too. Instead, due to unbelievable mismanagement in my opinion, we have returned to being a small club that had a brief period of good fortune, before retreating back to the lower leagues, BC Game, financial mismanagement, dreadful scouting etc. That doesn't detract from our successes, but its also a shame.
