If I wanted to capture something with HDCP, what’s the most straightforward path to stripping it away?

There are various splitters and mixers that have the necessary edid/hdcp emulator functions. I don't know if anybody has managed to figure out how to defeat hdcp higher than 1.4 though.

    Aside from the high number of 1-star reviews complaining about the gadget dying fast - how in god's name is this thing still selling assuming it can actually strip HDCP for modern HDMI standards? I'd have expected HDMI LA to be very very strict in enforcing actions against HDCP strippers. If not, why even keep up the game? It's not like pirates can already defeat virtually all copy protection mechanisms on the market, even before HDCP ever enters the field.

      > Aside from the high number of 1-star reviews complaining about the gadget dying fast - how in god's name is this thing still selling assuming it can actually strip HDCP for modern HDMI standards? How is 1 review a "high number of 1-star reviews"? There are a total of 32 reviews for this device, 2 of which are 1-star reviews. Only one of those warns "Stopped working in 5 minutes". The other 1-star review notes (in translation) "When I tried this device, I got another very bad device at a lower price". I'm not sure what your expectation that "HDMI LA to be very very strict in enforcing actions against HDCP strippers" means in this context. Indeed, your second paragraph seems to be an expression of consternation that manufacturers would go through the trouble of implementing HDCP given how easily it can be circumvented.

It used to be the case that HDMI LA would act very swiftly on any keybox leaks and revoke the certificates, as well as pursuing legal actions against sellers of HDCP strippers. These devices were sold by fly-by-night eBay and darknet sellers, not right on the storefront of Amazon. > Indeed, your second paragraph seems to be an expression of consternation that manufacturers would go through the trouble of implementing HDCP given how easily it can be circumvented. Manufacturers do because HDCP is a requirement to even be allowed to use the HDMI trademark, in contrast to DisplayPort. I was referring to HDMI LA and the goons of the movie rightsholder industry that insist on continuing this pointless arms race.

      Not even the finest lawyers can keep up with fly by night marketplace suppliers with company names that are just random letters

    As with the vast majority of products on Amazon, you could probably find the same on Aliexpress/baba for less.

      If you're in the United States you can expect hefty brokerage fees and tariff charges for anything arriving internationally starting on May 2nd. If the Amazon listing ships from the United States it's a better choice now.

HDFury has multiple devices that can do it, but they are fairly expensive. Many of the cheap HDMI 1x2 splitters on Amazon also strip HDCP on the secondary output. You can check reviews for hints.

My USB HDMI capture thing removes it. Wouldn't be surprised if the other no name ones did the same. It was only like $20 too.
