The phrase “if you’re not paying for the product, you are the product” really applies here. VPNs, especially in some countries, are a vitally important way to maintain your privacy on the internet. Don’t make the mistake of handing your privacy over to a shady company that can abuse it! Some of the well-established and trusted VPN services do require a subscription fee, but the competition between them has kept the fees affordable and it is well worth the cost.
Plus, don’t use any VPN based in China or downloaded from Chinese App Store, especially if you’re a Chinese citizen living in China.
Why would you think there are still usable vpns in App Store while they totally can ask apple to take all of them down? Why would you think the government only took down part of those vpns?
