No, no well known, or little known or even unknown company accepts altcoins. there are some small businesses online that are accepting old good altcoins such as Litecoin and dogecoin but nothing else.
however you will find a lot of falsified news saying some big company like Microsoft for example is accepting a shitcoin. for example all the lies about Microsoft accepting ether on the news sites. but you always need to check their official website like Microsoft.com and see for yourself. the only cryptocurrency that Microsoft accepts is bitcoin.
