Overall, certainly. There are some negative things people talk about that you might agree with, but look back at what the market was that they disrupted and continue to disrupt. I think that without Cloudflare your registrar would be GoDaddy and your SSL certificates would be from Verisign and your rents would be huge. Backbone wise, that would depend on your region.
My registrar were different before and after godaddy existed and plenty of varieties existed. I find less exist now than during GoDaddy's heyday. But less people care about domain names as they stopped becoming a lottery ticket.
My worries were paypal would take over but then came stripe.
SSL certificates were from Verisign until letsencrypt offered thek free. I didn't see Cloudflare changing that market.
Before them we had uunet and other backbone providers.
Cloudflare made their name from ddos protection attacks. They made that market.
