Correct me if I'm wrong, with many cdn providers you must use their free let's encrypt ssl, which make your premium ssl you bought elsewhere useless.
I not want this, I not want paying money for a fair price premium positive ssl, which helps prevent getting any browser "website not secure" warnings and replace this good product with a free ssl from an cdn provider, what a joke!
Or another trap, you must setup a domain, no, I not want make the cdn outrank my main domain .
Find a good cdn in the price range of $10-20 month, where you can use your own positive ssl and your main domain without using www, it's hard to find...
Best is have a good fast webhosting or dedicated hosting/ vps .
Traps overall the place to steal your online property you want to build up.
When I check big sites to learn from them, I not see that they use a cdn or free let's encrypt ssl.
