Wary you say? The bitcoin network actually needs companies like MicroStrategy and even bigger ones to join the network, I don't see any cons in it, it appreciates adoption and encourages other establishments to also come in. Btc's purpose btw isn't to survive as a currency, I don't think it matters at all what people or establishments do with btc when they buy it. That being said, if bitcoin is to serve as more of a currency, more adoption is of course needed and that can only one with more of this kind of news.
