Its called reader churn
They need to churn their readers as they need the $$$ from the cc apps from the newbies who think that flying in F is really free.
Many of us don't bother going to these blogs as they became boring and repetitive a long time ago. They lost the old readers, who don't use their CC links anyway, and need to replace them with fresh meat.
Many of those on this forum have flown in F on all the birds that are reviewed and we can form our own opinions.
