I tried reaching out to Cloudflare with issues like this in the past. The response is dozens of employees hitting my LinkedIn page yet no responses to basic, reproduceable technical issues.
You need to fix this internally as it's a reputational problem now. Less screwing around using Salesforce as your private Twitter, more leadership in triage. Your devs obviously aren't motivated to fix this stuff independently and for whatever reason they keep breaking the web.
I'm not saying this to say its a good thing; it isn't.
Here's something to consider though: Why are we going after Cloudflare for this? Isn't the website operator far, far more at-fault? They chose Cloudflare. They configure Cloudflare. They, in theory, publish an RSS feed, which is broken because of infrastructure decisions they made. You're going after Ryobi because you've got a leaky pipe. But beyond that: isn't this tool Cloudflare publishes doing exactly what the website operators intended it to do? It blocks non-human traffic. RSS clients are non-human traffic. Maybe the reason you don't want to go after the website operators is because you know you're in the wrong? Why can't these RSS clients detect when they encounter this situation, and prompt the user with a captive portal to get past it?
There will always be niche technologies and nascent standards and we're taking Cloudflare to task today because if they continue to stomp on them, we get nowhere.
"Don't use Cloudflare" is an option, but we can demand both.
I mean that somewhat sarcastically; but there does come a point where the demands are unreasonable, the technology is dead. There are probably more people browsing with JavaScript disabled than using RSS feeds. There are probably more people browsing on Windows XP than using RSS feeds. Do I yell at you because your personal blog doesn't support IE6 anymore?
