When I was looking for a plugin, there was 3 and out of those 3 this one was the perfect one, but I choose it because he had what I needed in the free version, but I definitely will upgrade later.
The problem with SSL was implemented by big corporations, I feel as a beginner programmer that the SSL is not really for security but for spying, it possible creates a special channel for corps to see what you do, which through https:// would be hard to achieve, but this is only in my theory, need to learn codding and to dig into it.
Also they want to harm small businesses with their SSL thing, now you will leave and find other plugin but this guy will be left without income.
If i had the power I would have removed SSL requirement from all websites.
Let’s not forget that some SSL certificates cost allot of money per year, this is another business model, problem/solution = profit.
