Huh? FCF is operating cash flow - cash flow from investing (mainly Capex and aquisitions). R&D and marketing are costs already included in operating cash flow unless (!) those costs are being capitalized. In that case, they are part of Capex and appear in the income statement only as part of depreciation.
Money left over is rather free cash flow than income. Other than that, I don't get your point. Intel doesn't see reduced profits due to investment being too high but due to increasing cost and only minor revenue increase. Pretty simple as that. In such a situation, the company should rather invest its free cash flow into new fabs and processes for a solid foundry business instead of distributing it to short sighted shareholders who don't or don't want to see the bigger picture.
