I feel completely betrayed by Adobe (Illustrator)

I argued with my boss and leads that designing presentations in Figma was not the way. I talked about Illustrator, and making top-tier presentations and PDFs. I sold them on it hard. I just spent a week re-doing a deck for them, and am now finding out that Illustrator's PDF export is totally broken. I used AI for print for over a decade, and have made hundreds of crisp PDFs. I can no longer export PDFs with images that look good. It is NOT possible. No matter the resolution of the source, no matter the downsampling option (if any it picked), every raster image comes out looking like a steppe pyramid. So much aliasing.

If I export each artboard as a PNG (only using the legacy option), they all come out perfectly crisp. ANY OTHER method of trying to get those images out of Illustrator makes them look like garbage. I feel so damned embarassed. I'm going to have to tell them we can't realistically do it this way (I'm not exporting individual PNG pages for everything).

I'm really disappointed in Adobe. I won't be prosetylizing their products anymore.
