They are after the personal use VPN clients, but corporate users will follow soon.
Using the corporate VPN for personal purposes, including social media, is generally against corporate policy and is frowned upon (at least officially) in most businesses and organisations. It is also fraught with complications and could lead to disciplinary action or other unpleasant consequences. Just because the policy is not enforced does not mean it won’t be in the future.
If governments start targeting personal VPN's, it is only a matter of time before businesses crack down on unauthorised corporate VPN use as it will increase their risk of legal action stemming from employees’ missteps or misdeeds.
