That's not really Cloudflare's fault. Someone has to do it, whether it's them or a competitor or sys admins manually making firewall rules. Cloudflare just happens to be good enough and darned affordable, so many choose to use them.
Hosting costs for small site owners would be much more expensive without Cloudflare shielding and caching.
Furthermore, they give Google preferred treatment in their UIs and backend algos because it is the incumbent and nobody cares about other smaller search engines. So there's a lot of detail to how they work in this domain.
It's 100% Cloudflare's fault, and it's up to them to give everyone a fair shot. They just don't care. Also, you are overlooking the fact that Google is a major investor (and so is Bing and Baidu). So really this exacerbates the issue. Should Google be allowed (either directly or indirectly) to block competing crawlers from dowloading web pages?
Nobody has to do it, but a lot of people will do it when they notice there's an easy way to do it. Cloudflare is very much an enabler of bad behavior here. Now a lot of sites just toggle that on without even thinking about collateral.
Um, this is America. Every market is basically a trust, cartel, or monopoly.
And I don't know if you can hear that, but there is literally laughter in the halls of power. All the show hearings by congress on social media and tech companies only has to do with two things:
1) one political party thinking the other is getting an advantage by them
2) shaking them down for more lobbying and campaign donations
No one in the halls of power give two shits about competition. Larger companies mean larger campaign donations, and more powerful people to hobnob with if/when you leave or lose your political office.
Of course I think that breaking up the cartels in every major sector would lead to massive improvements: more companies is more employment, more domestic employment, more people trying to innovate in management and product development, more product choice, lower prices, more competition, more redundancy/tolerance to supply chain disruption, less corruption in government and possibly better regulation.
Every large company brazenly does market abuse up and to the point of one and only one limiter: the "bad PR" line. So I guess we have that.
look at linkedin (owned by microsoft unspiderable by all but google/bing). github (now microsoft using this to fuel its AI coding buddy, but if you try to spider this at capacity your IP is banned) facebook (unspiderable) .. the list goes on and on ..
and as you can see, data is required to train advanced AI systems, too. So big tech has the advantage there as well. especially when they can swoop in and corrupt once non-profit companies like openai, and make them [partially] for-profit.
and to rant on (yes, this is what i do :)) it very difficult to buy a computer now. have you tried to buy a raspberry pi or even a jetson nano lately? Who is getting preferred access to the chip factories? Does anyone know? Is big tech getting dibs on all the microchips now too?
Cloudflare allows search engine crawlers and bots. If you observe crawl issues or Cloudflare challenges presented to the search engine crawler or bot, contact Cloudflare support with the information you gather when troubleshooting the crawl errors via the methods outlined in this guide.
Cloudflare is giving it's customers what they want. They don't want all kinds of bots claiming to be search engines crawling their sites. Cloudflare isn't hurting cloudflare competitors by doing this. Cloudflare isn't hurting their customers by doing this. To repeat - most websites don't want lots and lots of crawlers. They want the 2 or 3 which matter and no more, because at some point it's difficult to tell what the crawler is doing... (is it a search engine???). They aren't obliged to help search engines. Even if Cloudflare wasn't offering this, bigger customers would roll their own and do.. more or less the same thing.
