I get that you have been on this website a very long time, and that this feels like your safe haven; your home, if you will. And I understand that it feels infiltrated with pro-lifers, especially after all the media coverage it has gotten over the years. Of course it has attracted a lot of people who are anti-suicide, because the website is entirely shocking to the outside world. There is not one single strong opinion that will not have oppression, and that's the reality of being pro-choice on suicide. You will have to - to an extent - defend your argument if it is public. And for better or worse, SS is quite public.
All that to say, despite sympathizing with your sentiment, I don't know if I can fully agree. There has been a recovery board on this website for quite some time, thus proving that it was never simply for those who are moments away from ending their life. Further, there are people on here who are severely suicidal but do not have as much access or resources to follow through, so perhaps they just want to commune with like-minded people without being set on dying. Lacking resources might inspire force people to have to fight to stay alive, thus feigning an appearance of being pro-life. This website needs to be a safe place for both suicidal people, and those who are struggling yet are not set on a decision. Take yourself as an example: many have asked you why you are still on this website and have been for years, but have not caught the bus. Your answer almost verbatim is always "lack of resources and access" is it not? I'm saying this to prove the point that no two people are on SS for the exact same reason, and gatekeeping that is entirely messed up.
People who do come on here offering help are not harming anyone. You can simply ignore those comments if it isn't what you're looking for. Those who are out-right pro-life and full on anti-SaSu seem to get banned pretty quickly, no? I feel like the administration is damn quick to delete a user who says anything in the realm of being against what SS stands for. So I am not sure where the worry is coming from.
I wasn't here years ago, but I imagine SS was never just a pro-suicide website. There are people who come here because they may struggle with feelings of wanting to end their life, or major depression, or severe isolation but they may not actually want to die. They deserve to have community with people who are feeling suicidal at the same time as them. And if two people consensually end up choosing recovery together, then let them have this safe space to do it. A space that understands both wanting to kill yourself, and wanting to embrace recovery. That is what is so beautiful about SS in my opinion. You can be on either side of the fence (as in, suicidal or desiring recovery) and you can even have one foot in each side!
Take what you like and leave the rest. This is a public forum and an open community and if you do not want to have to defend your argument or hear another pro-life approach, simply scroll. Your safe space isn't gone but unfortunately when it comes to the internet, it will never be as secure as you'd hope. Stay away from the recovery based boards, and stick to threads that amplify your own agenda or desires. Suicide is always going to be controversial, even amongst a forum full of people who want to die. If you need solace from all of this, I suggest you stay close to those who understand you most and block out responses on the internet that you don't like
