Philistine Inscription from Ashkelon

The origin and the nature of the Philistines is now even more of an enigma. 

The recent Harvard Leon Levy Expedition excavations in the area of the port of Ashkelon recovered 18 jar handles and one inscribed ostracon made from local clay...

According to two researchers, Giancarlo T. Tomezzoli and Reinhardt S. Stein this inscription was written in Cipro-Minoan script. This is the table giving the characters from the inscription with most likely vocal values...

So far so good. 

Now the bad bit. Bad in a sense that it will take some explaining and I can't wait to hear it. 

The proposed reading of the inscription is [L] *IUDI PADI PA WEDIMI, which according to the researchers is "Proto-Slavic inscription meaning 'People, come and see'"...

I would say that wedimi could also be "say to", "teach", "pass knowledge" which are all meaning of the word "ved" (wed) which means knowledge...In which case the meaning could be people "come to pass knowledge"...

Giancarlo Tomezzoli and Reinhardt S. Stein published their findings in "The Philistine Inscription 4.5 from Ashkelon (Israel)"

We know that recent genetic data points to European origin of Philistines...

So what the hell is going on? 

The researchers are not Slavic by the way, so their nationalistic bias is out of question I think...
