> There is no legitimate use for it in this context
There's no legitimate usage for World of Warcraft on a work computer, and I'd happily ban that from work computers. But I also wouldn't hop onto an unrelated article for new players and imply that all of them were criminals. The linked article never mentions work computers, it's talking to website operators.
If your objection here is that you think Tor is inappropriate at this moment in one specific work setting, then fine, but that's not really adding anything to the conversation about whether or not general websites should be made available over Tor. It's just unrelated FUD.
I want to be clear, the goal of Tor proponents is for everyone to be running Tor (or something similar), and for most websites to be available over Tor by default. People should be running Tor on their smartphones, on their home laptops. Tor should be the default way that people share files with each other, and the default way that people set up technical blogs, or even just quick websites that show off pictures of their cat. The vision of the Tor project is a world where Tor is normal and ubiquitous for regular, non-technical people.
So unless your work policy bans all personal devices from your network, creating an expectation that any smartphone that joins and boots up a Tor browser automatically belongs to a criminal is contrary to the goals of the privacy movement. Our goal is that every device and every website should be private by default. Your network should be the exception, and it should only have company-owned devices on it.
And of course it's fine if you disagree with that, you don't have to be a privacy proponent. Lots of smart, reasonable people disagree with us about what the balance is between security and privacy. But demonizing Tor users in ordinary, everyday contexts is anti-Tor.

To go a step farther and suggest that making a website available over Tor should automatically mean that people who visit it are suspicious -- that is also anti-Tor and (I would argue) anti-privacy in general.
If I went into an interview for any company in any field offhandedly mentioning that I ran a Tor website, and then had to field a bunch of questions about whether or not I was a criminal, that would be a major red flag to me to avoid that company.
