I have seen that Bitcoin.org is using the API of Blockchain.com for its donation button. [thinking]
If you pay attention to the Bitcoin address listed on https://bitcoin.org, it is a Segwit address (P2SH); As far as I know, currently, blockchain.com (previously blockchain.info) only supports legacy (P2PKH) receiving addresses.--Does the blockchain.com web-wallet support spend-to-segwit and/or spend-to-bech32--
As OmegaStarScream mentioned, they only use it to retrieve the Bitcoin price in USD.
