 that it is a solution. I think Facebook will put a lot of other social media platforms, gives a lot of benefits, especially for our social network. It's very easy to maintain our social network via social media, but nothing is for free in this world, so also not Facebook or Instagram or Snapchat. We use it for free, it doesn't cost us any money, but it costs us data. They use our data, and that is known since the early days of Facebook and all the other platforms. So if you don't like that, okay, then you can leave Facebook or social media, but then I would advise you to stay away from the internet as much as possible, because also using Google gives Google a lot of data and they use it. They do it already for many years and they will do it even more in the future. Our studies show that we do not become more or less happy, so this does not have any effect on happiness, but it has some social effects on social capital. We have found that in our research, but also a lot of studies in the U.S. found that if you use social media, it benefits your social capital. And we also found a few effects on social competence, and that especially early adolescents who are using Facebook, they get more social competence, not only online, but also offline. On the one hand, there should be regulations. There are regulations, by the way, but for the normal use of our data for commercial purposes for advertising, there are regulations. And in these regulations it also said that what happened with Cambridge Analytica is not good. So in fact, but it should be tested more, and I think that is a task for the governor. On the other hand, I think we as users should be aware that our data is used. We cannot use it for free without the company uses our data. That's impossible. Or we should accept that we have to pay a fee every month and then they cannot do those things. That's one thing. Or if we know it's for free and they use our data, we should be very much aware of what we post online and or realize that we have to pay for it. And then then we can ask them not to use our data. But still, the control is something, of course, you expect that the ethical consciousness and the moral of the company is good enough. But in the end, it's all about the money. So we should not leave it to the company alone. There should be more parties, stakeholders involved.
