I think Cloudflare WAF is a good product compared to other WAFs - by definition a WAF is intended to layer on validation that properly built applications should be doing, so it's sort of expected that it would reject valid potentially harmful content.
I think you can fairly criticise WAF products and the people who advocate for them (and created the need for them) but I don't think the CF team responsible can really be singled out.
