You are collapsing the two studies into one here to make this point. Note what I said:
Yes, many labs have followed up on Lombardi et al, but I'm not aware of any that have followed up on Lo et al. That is the point. After 2 decades of ignoring this disease the "leading retrovirologists" show up with a singular, strikingly-negative focus on Lomardi et al while continuing to ignore the remainder of supporting evidence.
But I'm being generous by saying "followed up". All the efforts of the "leading retrovirologists" have been toward discrediting and disproving HGRVs, and specifically directed at Lombardi et al. There is a marked difference between discrediting/disproving and scientifically following up. Luckily, this difference is also discernible. The former can be distinguished by a number of bad faith actions: declaring you will not find something before you even begin; overreaching and definitive conclusions; unwillingness to collaborate closely with the original authors (Bieger is the only exception to this); insistence that a novel discovery be fully understood a priori without any willingness to acknowledge the inherent exploratory nature of novel discoveries; ignoring and misinterpreting data supportive of the original discovery (Lo et al, macaque study, etc); coordinated (always negative) media campaigns; appeals to "consensus" and numbers of studies without evaluation of the particulars of the data; calls for retraction on the basis that a paper is "wrong" (remember Stoye and Coffin have been calling for retraction for many months now); blocking funding to and further publication from the original discoverers, then lambasting them for speaking about data prior to publication; blocking the authors of potentially one of the largest retrovirology discoveries in a couple decades from presenting at top retrovirology conferences; a marked asymmetry in establishment criticism directed toward positive studies; actually trying to claim that exact replication is not important; etc.
We've seen these actions and behaviors in spades now for two years. And I'm supposed to accept that these actions represent a good faith, genuine scientific effort? Please.
The only time this has happened for Lo et al is in the recent BWG paper, and I've already provided for you a number of factors that make this, at the very least, not as black and white as you keep presenting it.

No evidence of murine-like gammaretroviruses in CFS patients previously identified as XMRV-infected.

.......
We found no evidence of XMRV
or other MLVs in these blood samples. In addition, we found that these gammaretroviruses were strongly (X-MLV) or partially (XMRV) susceptible to inactivation by sera from CFS patients and healthy controls, which suggested that establishment of a successful MLV infection in humans would be unlikely.

...Using highly sensitive and generic DNA and RNA PCR tests, and a new Western blot assay employing purified whole XMRV as antigen, we found
no evidence of XMRV or MuLV in all 45 CFS cases and in the 42 persons without CFS. Our findings, together with previous negative reports, do not suggest an association of XMRV or MuLV in the majority of CFS cases....
