"a currently questionable fascination" is just poor English. Fascination with celebrity has probably always been distasteful to the writer not just currently. Their use of the word "questionable" is probably meant to indicate that they doubt the celebrities are worthy of the interest shown but it just confuses things to write "currently questionable". It is confusing and untenably conflates the current pervasiveness of the fascination with it's distastefulness and with the disreputability of it's subjects.
The writer is probably just jealous.
