Tech companies regularly use both GAAP and non-GAAP in their statements, and for good reason, so non-GAAP should not immediately be dismissed.
GAAP is very much the bottom line - it's damn near every penny spent and earned accounted for in the final income statements. Importantly, this includes both the core business and one-off gains/losses such as settlements, restructuring costs, and write-downs. This is very important for investors as it means a company can't simply hide certain types of charges, so if a company lost a ton of money on such charges investors will see it on the bottom line.
However because GAAP includes those one-off charges, it's not very good for comparing the core business on a quarterly and annual basis. As a result tech companies will almost always compute both GAAP and non-GAAP financial results, with non-GAAP results throwing out one-off charges (and a couple of other changes) so that investors can see the results of just the core business, with all of the noise thrown out. This allows investors to evaluate the core business on its own, so that they can see whether the company would have been healthy outside of those charges, or if the core business is suffering too.
Both are important, and that's why both are included. Despite what you may think there's nothing devious about it; including both instead of just GAAP means that investors can quickly see and track the financial status of both the company and the core business. News articles in turn may quote one or another (or both), but this is purely optional on their part. On the actual reports you will always see GAAP regardless of whether non-GAAP is included too.
