Salesforce doesn't get dragged into anti-tech sentiment because they build a b2b product. The Twitter activists who lead most of the anti-tech crusades don't know what CRM is or what it does because they
never interact with it because they are unemployed.
The people who do use Salesforce for the most part hate it. But you'll never see widespread outrage about Salesforce because the people who use it have jobs, families, and friends that prevent them from spending all day on social media.
What makes you think "twitter activists" lead most of the anti-tech crusades? If it's based on your observations of them on twitter, that probably says more about where you're looking than where they are. I don't know where anti-tech activism is centered, but twitter wouldn't be my first guess.
Maybe the quoted author was a bit flippant in their comment, but to put it another way, wouldn't you agree that if someone were to say "Salesforce is letting people spread fake news" or "Atlassian has a contract with ICE" that there would be relatively less interest and clicks on the headlines? The fact that the consumer-oriented tech companies are on peoples' minds makes a difference whether it's worth going after them.
