They don't care
"Novella discovered the first problem in April 2013 and the second in September. He has notified the ISPs and hardware vendor, but says he has yet to hear back, prompting his decision to go public last week.
"Neither Movistar nor Pirelli answered my attempts for fixing the problems," said Novella. "Only Arnet Telecom Argentina replied the first email. After I explained the vulnerability, they disappeared and never got a message back."
El Reg asked ADB Pirelli for comment on the reported vulnerabilities last week, and received no response. We'll update this story as and when we hear more. "
Frankly, El Reg shouldn't hold its breath, as Novella has apparently aited for one and a half year, for no answer :-)
This gives credit to Google blackmailing strategy (3 months, then go public) towards Microsoft.
Simply, to any SW vendor, security is customer's problem. They don't care.
