Slack is being bought out for ~26$ per share and ~.07 shares of Salesforce in Q2'2022; so is Slack's current price then going to be pinned to Salesforce's stock price? I'm assuming that's why one shouldn't assume selling LEAPS against slack is just free money, merger arbitration aside.
That is one of the best messengers for business and freelancers which exists these days. In our company we use twilio slack for example in order to deal with all our customer complaints and requests in the real time. Clients seem to be happy and it has a direct connection to the level of our income.
