The answer is obvious and it s yes, bitcoin will be more accepted and be used by people, people trust PayPal. But, people will be ignorant of the fact that PayPal is just a third party, some people will not know about private key at all, which is still the continuation of centralization. But the main aim of bitcoin creator was to make a currency that will be fully decentralized but this is being compromised by the centralized world. But, people that know about bitcoin very well and have expert view about it will still be able to use bitcoin in a decentralized form but while many people are not bother, in one way or the other, people that are not bother are susceptible to scammers and hacks, although, it can be indirectly.
