I was curious so read into it.

It seems like they never figured out how to do the seamless checkout that Google wallet and Apple Pay provide and also seem to being out maneuvered by Stripe too.

I always thought their big play was being another payment platform outside of Visa and Mastercard, but maybe they never leveraged that the way I thought they should.

In addition to the below comments, PayPal is also one of the few major platforms who add a fee for Chargebacks which leads to frauds where users could send money to a YouTuber, Gamedev, or Streamer via a paypal link, let's say $1, and then take the money back, resulting in a $15 loss to said Streamer.

There were a couple of high profile cases of this a while back where PayPal saw this happen and chose not to settle the fees, because it was within their terms to charge them regardless of the cause.
