I've used Paypal for a number of years without any drama, primarily for person to person transactions, or the infrequent eBay purchase. Paypal fills a niche for these types of transactions, not everyone has Venmo or Zelle. My online purchases from established concerns (e.g., Smoking Pipes) are made using a credit card, buyer protection is okay and there are rewards to be had. If Paypal makes it difficult for folks to trade in tobacco and tobacco products I suppose those transactions will transition to other means, Venmo, Zelle or how about money orders.
I do wonder what's behind the move by Paypal, I doubt it's their corporate interest in our health. Without some sort of external driver (legal or tax issue) how long will they want to deal with managing the whole permission thing, leading either to policy abandonment or forbidding any sort of tobacco related transactions?
