https://www.web3.foundation and https://www.webfoundation.org and https://www.wc3.org seem/sound related, so are these organizations related?
Web3 Foundation's (Polkadot) writing nearly implies it is related er connected to WC3 or WebFoundation.org (Tim Burners-Lee, https://en.wikipedia.org/wiki/Tim_Berners-Lee the founder of the Internet), and search engines show a questionable order when searching "Web3 Foundation" which might appear to be the WC3 or WebFoundation.
I know many people are not familiar with Polkadot, given it's not very old. In the news are lots of stories about "parachains" of which made DOT popular. Coinbase and others have heavily supported these efforts. I was surprised to read DOT research papers and other sources repeatedly describe their efforts with nearly the equivalent language as W3C uses when describing their standardization efforts, which might as well be copy/paste from W3C advocacy. I doubt I am alone thinking DOT was literally replacing W3C, from their language usage. There is a tone/suggestion of somehow DOT recruiting all the experts from W3C, and W3C governance becoming DOT protocol governance.
(I chatted about https://view.matrix.org/room/!TawyRKRXPWmCJVthoT:matrix.org/?anchor=$1640295609873591AQvAS:matrix.org&offset=90 [1][2][3] this phenomenon because it could seem to be an attack vector nearly, there is a risk people might confuse these three organizations?)
