Maybe this approach would have made sense if the area were an established hub in whatever craft those immigrants are specializing in, but in case of Portugal what I can see is a country with (formerly?) cheap CoL trying to attract immigrants who keep working remotely, paying taxes elsewhere and contributing whatever little consumption tax they pay into the local economy. There's no established competitive IT industry or academia. This isn't how you build high-tech economy, it's how you become a suburban wasteland for rich people.
Some countries including my home country Poland impose a ban on political agitation on the election day. It means that no political content may be published on that day, but whatever has been published before that is allowed to stay. This is an old law which predates the Internet, so anything from social media posts to hanging up election posters is liable to be prosecuted and the authorities frequently do so. It's less drastic than in Pakistan, more drastic than in the West, but it certainly does cause a chilling effect on people when they know they may lose a few thousands if they get caught.
I find it to be coincidental to the general interest in mental health and the resulting wave of self-diagnoses. It has its positive sides - even I did eventually seek psychological help after going through all the resources available online - but I've also met people in real life who collected personality disorders like badges of honor. There's one couple I know who only formed a strong bond after she's convinced him that his family is toxic and he should go no contact with them, just as she did long time before that.
I would be more concerned about accuracy, bias and curation sooner than I would think about the license in case of a community-built dataset. Take a website such as TasteAtlas, for example. They frequently publish rankings of best/worst foodstufs, but their data on that is garbage (even if you skip the fact that taste is highly subjective). Not only are there lots of incorrect assumptions made (e.g. a dish always belongs to only one national cuisine), but also the popularity data is not curated at all, so they end up with situations such as the first place in my country on the "100 Best Food Destinations" list was a tiny village with a truck stop.
