The word "implicated" in science normally means "correlated with" and can't really be considered a "solid link".
Some of the articles cited in that section have sentences like "1 out 2 (50%) adult analyzed cases was positive, with 50% of stained tumor cells (this patient was a 22 years old female, coming from Napoli);" that don't follow the necessary standard of evidence. I continued to skim the linked articles and they are all clearly correlative.
It's a lot more subtle than that. First off let me say that historically, demonstrating that a virus causes cancer has been a major bit of work, and many times people have mistakenly seen associations and falsely believed they were causal. second, I don't deny there are some cancers which are caused by viruses. But, you're referencing extremely rare cancers, not the cancers that make up the bulk of US (or world) deaths from cancer. My complaint is about taking these relatively rare situations and implying there's some sort of general underlying well-understood cause, when the reality is, in many situations, the virus itself did not specifically "cause" the cancer, but for complex biological reasons, it's "associated" with the cancer (which could manifest as increased susceptibility to getting particular types, or worse prognosis, or even possibly better outcome).
