It’s a deadly blow for the company. Since the news that the two largest broadband providers have withdrawn their support Phorm's share price has dropped a whopping 53 per cent.
That dread news came hard on the heels of claims that the delays to the roll out of its service, which it blamed on UK broadband suppliers, are costing the company £1 million per month.
It’ll be interesting to see if other ISPs join the exodus away from Phorm in the next few days. If they do, it seems that we’ll finally be free of the threat from behavioural monitoring and targed ads, allowing privacy campaigners to rest easy. For now at least, anyway.
