We remember that day when the news came out. BTC shot up from $38K to 44K and to 48K the day after. People expected an avalanche of big companies to buy BTC. So far it hasn't happened yet it seems. We have seen news about some companies around the world buying crypto but they were not "big" big players like Tesla. Do you think corporate buying so far was not as big as we expected when Tesla made the news?
There were big names/players that already were into Bitcoin specifically. Not sure if they purchased, but if adopting/including it as payment method would count then Microsoft did already back in 2014. They were now surveying actually for Xbox users if they would like to pay through Bitcoin though. From what I read, they continued accepting Bitcoin payments from its halt before.
Valve adopted Bitcoin payment to their Steam platform before though, but it got pulled out for obvious reasons of "high fees and volatility"
