Cause the law is highly staked in the direction of the claimant with DMCA. First, only the real copyright owner can go to court against them (so, you cannot take look, find out they aren't the copyright holder and then sue them), then you need to see the case through and if there's anything these big companies have it's dozens and dozens of lawyers on the clock, while the other side will probably have to pay per hour. And even if you make it to the end they'll probably get off on some technicality, cause "oh, we really, really thought we had the copyright, we are so sorry" and even if not any damages will be laughable compared to the upside of them filing claims left and right. It's just a shitty system all around. Exactly as intended by the companies that pushed for it. (IANAL. All based on reading up on the topic once when I had the same thought)
