Do you have any reason to believe that intelligence agencies are involved in the cases mentioned? Why would they? Please cite.
Former workers are sometimes just that.

You claimed that Israel's agencies had something to do with what the article above is discussing.
You should provide evidence.
(and no. The fact that former intelligence workers have roles in a related private company is not evidence of the country's involvement. Many companies employ or are managed by former intelligence workers. If you think they're all controlled by the Israel Mossad you should probably stop using firewalls/routers/CPU chipsets. Good luck)
