This topic deserves so much more nuance, but it's always reduced to "barefoot running doesn't work" in internet forums. In every articles about the harm caused by barefoot running I've read, those reported injuries all end up being overuse injuries. The article you linked is specifically about bone marrow edema, which is basically bone bruise. Other possible injuries include muscle and tendon soreness.

If this were a bodybuilding discussion, you would get advice on how to manage DOMS symptoms and how to plan your loading schedule, nobody would say that weightlifting "doesn't work" because a beginner got sore after lifting a 80kg barbell for the first time. But people has been conditioned to think that running is a purely cardio activity, so we don't talk about how the muscles and tendons in the foot need to be loaded up gradually just like your bicep.

Barefoot running is a weightlifting activity. Your calf muscle has to lift your entire bodyweight for the forefoot stride. "No pain no gain" applies. Proper posture and techniques are important. Proper workout schedule and loading plan with rest days are important. Sufficient protein intake are important.
