A long while back I came across a post on an old Buddhist forum about sharing your spiritual practice with others, telling loved ones about it, etc. I lost the link to the response I liked, but it went something like this.
Your practice is something you do to better yourself, to clear your own mind and find a higher purpose. And in doing so improve your relationships with others. It's natural to want to share something that has done you a lot of good with others, but very likely it won't be appreciated by them the same way you've appreciated it.
If you practice in private, and that changes the way you behave around others, they will notice, but not having anything to explain the change, they'll probably pass it off and think about something else. Your relationship may improve, and others can't really put their finger on why.
But if you do tell them, then you place that anchor in their mind. When you change, the attribute it to your practice. They may think, "oh he's changing because of that spirituality thing. I don't like it." That lack of validation will eat at you too, because you initially shared it in the hope of acceptance.
Well this is all to say that there's a lot in common between a spiritual practice and diving into freedom tech. In essence they're chasing the same goal. So in my view, the benefit of keeping it private outweighs the gamble of finding acceptance from others. It's a personal journey, and it's best to keep it that way. By improving yourself you improve others, even if they aren't aware of it. Sometimes especially because they're not aware of it.
