Eh, their revenue was $279 million, and profits at $75m. Growth at 30% p.a. so it really depends how long-term their investment outlook is and how much they believe growth will continue.
Particularly considering they own multiple VPN providers, so can probably squeeze overheads to increase margins, and also that much market control might allow you to increase prices across all brands you own due to reduced competition (as long as you don't tell anyone that's what you are doing - naughty naughty).
Of course foreign governments are already at the heart of all these VPN providers anyway.
With the rise of dictatorships worldwide and the complete inability of liberal democracies to fight back, I would guess there's a lot of growth in this market
I'd hope not, but I don't think it's a necessary conclusion. Most subscribers to VPN companies pay $5 or more a month and use almost zero bandwidth (basically just opening Facebook and Twitter here and there), and so it's easy to throw literally thousands of them onto a single high-throughput dedi. The ones with good marketing are very high-margin companies with a high LTV.
