Except the Parker and Ginobili decline was more coincidence than Aldridge's presence in a Spurs uniform. You were calling Parker's decline in 2014, well before the Aldridge signing. Manu fell off a cliff after the 2014 season and again, that had nothing to do with Aldridge. Diaw had been overrated for some time then, had a postseason rebirth against the Clippers in 2015. The style of play neutered Green's game. He simply doesn't function in the half court (that's largely due to Parker's and Manu's decline- inability to breakdown defenses through penetration, playing at a slower pace to conserve energy. etc.) and offensively, outside of a couple postseason bursts here and there, he hasn't been effective since he got paid (same with Diaw). Paddy is very limited to what he can do on the court (sub par passer, struggles to dribble and run at the same time) but if you're suggesting that Aldridge is the reason Paddy can't find the bottom of the net on wide open jumpers, think again.
The beautiful game was dead and buried after the 2014 season, before the arrival of Aldridge. It had already switched into a Kawhi-centric offense in 2015 which meant more isolation and post ups and much less ball movement. It's convenient to blame Aldridge for all the Spurs woes, but not very practical when you consider all the elements in play.
